Question

what is the distance between object and image, when object is kept infront of convex lens at centre of curvature

Answer 1

Answer:object has its own specific area and it contains many atoms and a picture is made by adding pixels in every area of it.

Explanation:

Answer 2

4R is the difference between the distance of object and image.

Explanation:

• It is given that we have an object placed in front of the convex lens.
• The distance of centre of curvature from the lens is 2 times the radius of curvature of the sides.
• Now coming to the properties of convex lens ,convex lens has the prioperty of converging rays.
• A ray coming from infinity would converge to focus on the other side of the lens .
• Similarly a ray coming from centre of the lens would converge and form the image on the opposite side of the lens at the centre of curvature on the other side of the lens.
• The distance of centre of curvature from the lens is 2R hence the total distance between them would be 4R.
