When light travels from rarer to denser medium the speed decreases does this decrease in speed imply?

Solution : No, reduction in speed on passing from a rarer to a denser medium does not imply a reduction in energy of light because the frequency of light remains unchanged and the energy of a light photon depends only on its frequency.

When a light wave travels from rarer to denser medium the speed decreases does it imply reduction its energy explain?

Solution : When light travels from a rarer to a denser medium, the speed decrease, but energy carried by the light wave remains unchanged. Energy of light depends on its frequency and number of light photons in given light beam and both these quantities remain unchanged.

When light travels from denser to rarer medium does the speed increase or decrease?

The correct answer is (B) Increases. When light travels from denser to rarer medium, the velocity of light increases, which results in the bending of light away from the normal.

When monochromatic light travels from a rarer to denser medium does the decrease in speed imply a reduction in the energy carried by light wave?

Solution. The energy of the wave depends only on its frequency. Since the frequency does not change as the wave travels from one medium to another, therefore, the energy of the wave remains same and does not decrease.

When light travels from rarer to denser medium its speed decreases True or false?

Hence, in a medium of greater optical density (optically denser), light will travel slower than in a medium of lower optical density (optically rarer). Therefore, when light travels from a rarer to a denser medium, its speed decreases. Therefore, the correct option is B) decreases.

When light travels from a rarer to denser medium, it loses some speed. Does

What happen when light travels from rarer to denser medium?

When light travels from rarer to denser medium,speed decreases, and when it comes out from denser medium speed increases...we know that if a body changes its speed or acceleration.. force needs to be applied...so which force makes it to speed up or slow down..

When a light travels from rarer medium to denser medium then?

When a ray of light passes from a rarer to denser medium it bends towards the normal.

When monochromatic light travels from a rarer to denser medium explain the following?

(i) When light travels from a rarer to denser medium, its frequency remains unchanged. It is because, frequency is an inherent property of light.

When monochromatic light travels from rarer to denser medium explain the following reasons?

When monochromatic light travel from a rare to denser medium explain the following is frequency of reflected and refracted light same as incident light does decrease in speed imply a reduction in energy carried by light wave.

When a light wave travels from denser to rarer medium its velocity decreases wavelength increases frequency remains unchanged?

The correct option is B wavelength. Explanation:Velocity of function of frequency and wavelength frequency remains same while moving from one medium to another. Hence velocity decreases because of change of wavelength. Light waves travel from optically rarer medium to optically denser medium.

When a monochromatic light passes from denser to a rarer medium its frequency remains constant and it bends away from the surface?

Answer: When a monochromatic beam of light passes from a denser medium to a rarer medium (a) Its velocity increases. Explanation: As light passes from denser to rarer medium, it bends away from the normal by following the Snell's law.

When monochromatic light travels from one medium to another its wavelength changes but frequency remains the same explain why?

Solution : Because refractive index for a given pair of media depends on the ratio of wavelengths and velocity of light in two media but not on frequency. So, frequency remains constant during refraction of light.

When monochromatic light is incident on a surface separating two media then both reflected and refracted light have the same frequency as the incident frequency?

Light incident on such atoms forces them to vibrate with the frequency of light. As the light emitted by these charged oscillators is equal to their own frequency of oscillation, so both the reflected and refracted lights have the same frequency as the frequency of incident light.

What is meant by a monochromatic light?

Monochromatic lights are single-wavelength light, where mono refers to single, and chroma means colour. Visible light of a narrow band of wavelengths is classified as monochromatic lights.

Why is frequency reflected and refracted?

Solution : The frequency of reflected and refracted light remains same as the frequency of incident light because frequency only depends on the source of light.

Can two independent monochromatic light sources be used to obtain a steady interference pattern justify your answer?

a i Light waves originating from two independent monochromatic sources will not have a constant phase difference. Therefore these sources will not be coherent and therefore would not produce a sustained interference pattern.

How does speed of light decrease in denser medium?

Light moves slower through denser media because more particles get in its way. Each time the light bumps into a particle of the medium, the light gets absorbed which causes the particle to vibrate a little and then the light gets re-emitted.

When a monochromatic light is refracted from a medium of refractive index 1.72 into vacuum its wavelength?

Hence the wavelength increases by 72 %

Does monochromatic light have same frequency?

The word monochromatic is not meant to imply that there is exactly one frequency in the light. Rather, it is meant to imply a very narrow range of frequencies contained in the light such that, for many practical purposes, we can approximate the light as only containing one frequency.

When monochromatic light falls on a photosensitive material the number of photoelectrons?

When monochromatic light falls on a photosensitive material, the number of photoelectrons emitted per second is n and their maximum kinetic energy is Kmax. If the intensity of the incident light is doubled, then. Both n and Kmax are doubled.

Do the frequency and wavelength change when light passes from a rarer to a denser medium?

when a ray of light passes from rarer to denser medium , its frequency remains same but wavelength changes .

When light goes from one medium to another the characteristic that remains and an effect is its?

The property of light that does not change when it travels from one medium to another is frequency.

Why wavelength changes and frequency remains the same?

Wave speed, frequency and wavelength in refraction

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

When a beam travels from denser to rarer medium if the incident angle is equal to the critical angle the refracted beam?

Detailed Solution

CONCEPT: Total internal reflection (TIR) occurs at the interface of two transparent media when the ray of light travels from a denser medium to a rarer medium. The critical angle is the angle of incidence in the denser medium for which the angle of refraction in the rarer medium is 90°.

When light travels from an optical rarer medium to an optical density medium the speed decreases because of change in * 1 point wavelength frequency amplitude phase?

Solution. When light travels from an optically rarer medium to an optically denser medium, the speed decreases because of the change in Wavelength.
