Question

When an object moves closer to a concave lens, what happens to the image formed?​

Answer 1

ANSWER

When object moves closer to convex lens, the image formed by it shift

A.away from the lens

B.towards the lens

C.first towards and then away from the lens

D.first away and then towards the lens

AnswerA

Solution

Image is shifted away from its focal point towards infinity as object moves from infinity towards optical centre of the concave lens.

Answer 2

Answer:

Concave lens

Explanation:

• In a concave lens, when an object is situated at infinity, image is made of focus in lens and here the object will be closer to the concave lens.
• A concave lens is defined as a lens which will deviate from the straight line because the image is made of a lens with the focus and the object will go closer to the concave lens.
• The image will be transferred from the focus that is towards a lens of size.
• In the concave lens, when an object is seen positioned in a infinity angle, the images is clearly made of any lens that is in focus, and an object will travel very close to concave lens. Again, the image can be seen transferred from a focus point of view towards the lens size.

Hence, the concave lens is present within the virtual image.
