What is the relation between focal length object distance and image distance?

1 Expert Answer

The key equation is the lens equation: 1/p + 1/q = 1/f where p is the object distance, q is the image distance and f is focal length.

What is the relationship between object distance image distance and focal length of convex lens?

When the object is moved closer to the lens, then the image distance also decreases. At the point of 2f, the image distance and object distance will be the same. For the further decreasing of object distance, the image distance will approach the infinity. So focal length will be half of the 2f.

How are focal length and image distance related?

The image distance is the distance from the thin lens to the image. The focal length is a characteristic of the thin lens, and it specifics the distance at which parallel rays come to a focus.

What is the relationship between focal length f object distance u and image distance for lens?

The focal length (f), object distance (u) and image distance (v) for a mirror according to mirror equationare related as f^-1=u^-1 + v^-1.

How are the image distance and object distance related?

Answer: The object distance and the image distance are inversely proportional.

Object image and focal distance relationship (proof of formula) | Physics | Khan Academy

What is the relationship between object and image?

An image is the point of convergence or apparent point of divergence of rays after they interact with a given optical element. An object provides rays that will be incident on an optical element. The optical element reflects or refracts the incident light rays which then meet at a point to form an image.

What is the relationship between distance of object you distance of image V and focal length f for spherical mirror?

v1+u1=f1.

What is the relation between object distance image distance and radius of curvature of the mirror?

Let PF = f, the focal length and PC = R, the radius of curvature of the mirror. AB is an object placed in front of the mirror perpendicular to its principal axis. A' B' is the virtual, erect image of the object AB formed (behind the mirror) after reflection at the convex mirror.

What is the relation between the two distances mirror to the object and mirror to the image explain with example?

Object Distance and Image Distance

That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must focus at a location 2 meters behind the mirror in order to view your image.

What is the relation between the image distance and focal length under what condition is this true?

It relates the focal length (f), the object distance (d_o) and the image distance or distance from lens to sensor in the case of a camera (d_i). The equation is the following: 1/d_o + 1/d_i = 1/f. the distance is close to the focus f.

What is difference between object distance and image distance?

The object distance is the distance of the object to the centre line of the lens. This is denoted by the symbol do . The image distance (sometimes confused with the focal length) is the distance of the image to the centre line of the lens. This is denoted by the symbol di .

What is the relation between the object distance and the image distance in a plane mirror?

For plane mirrors, the object distance (is equal to the image distance. That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must look at a location 2 meters behind the mirror in order to view your image.

How does focal length of concave mirror vary with object distance and image distance?

No Change in focal length.

Half of the radius of the spherical mirror is called the focal length OR focal length is the distance between the focal point and pole of the mirror.So it is independent of Object distance and image distance. There is no impact of object distance on focal length.

What is the distance between the image and the plane mirror if the object is at 15?

If an object is placed at 15 cm in front of a plane mirrot, where will the image form? In the case of the plane mirror, the image will be formed at the same distance behind the mirror as the object in front of the mirror. Thus the image will be formed 15 cm behind the plane mirror and will be virtual and upright.

What is the relation between UV and f?

The relation between u,vandf for a mirror is given by f=u+vu×v.

What is U and V in mirror formula?

The distance between the object and the pole of the mirror is called Object distance(u). The distance between the image and the pole of the mirror is called Image distance(v). The distance between the Principal focus and the pole of the mirror is called Focal Length(f).

What is mirror formula class 10th?

Hence, the equation of mirror formula is 1f=1v+1u. Note:The reflecting part of the concave spherical mirror is that which caves inwards and the reflecting part of convex spherical mirror is one which caves outwards. In convex mirror focal length f is positive and object distance u is taken as negative.

How does focal length change of object distance?

Solution : No, we cannot change focal length of a spherical mirror by changing the object distance (u), By changing u:v will change, but f will remain the same.

What is the distance of the object from the mirror and the distance of the image from the mirror?

The distance from the image to the mirror is always identical to the distance from the object to the mirror. So if a person stands 2.0 meters in front of the mirror, then the image will be located an identical 2.0 meters behind the mirror.

What is the distance between a person and the image formed in a plane mirror if he is standing at a distance of 50 m from the mirror?

Answer: Solution: (iii) 6m.

What is the formula of plane mirror?

Formula for number of images formed by two plane mirrors incident at an angle θ is n = 360∘θ. If n is even, the number of images is n-1, if n is an odd number of images.

What is the difference between focal distance and focal length?

Focal length in photography comes up far more often than focal distance, which is an entirely different property of a lens. Focal distance is related to focal length but is not dependent on it. What is this? Focal distance is the distance between the subject you are focusing to the camera sensor.

When object distance is less than focal length the image is?

Explanation: When the object distance is less than the focal length, the image is inverted relative to the object. When the object is at the center of curvature, the image is formed at infinity. When the object distance is larger than the focal length, the image is upright relative to the object.

What happens when focal length is greater than object distance?

In Figure 1, the object distance is greater than the focal length of the lens. The ray diagram shows that the image is formed where the three principal rays converge on the far side of the lens. As is apparent from the diagram, the image is larger than the object.

What happens when the object distance is less than focal length of a concave mirror?

A virtual image is formed if the object is located less than one focal length from the concave mirror.
