What happens to the image, if a convex lens is made up of two different transparent materials, as shown in the figure ?
Answers
Answer:
in this case , 2 images , at different distances will form with same or different intensiti4
Explanation:
2 materials have different REFRACTIVE Index and focal length.
Answer:
The lens is made up of two different transparent materials.
The above portion of the lens is made up of one transparent material whereas the below portion is made up of the other transparent material.
As we know different materials have different refractive indexes as well as different materials have different focal lengths.
Hence, it is obvious to get two different images from the lens.
The light rays which will fall on the above portion of the lens, will form a different image; and the light rays which will fall on the below portion of the lens, will form a different image.
______________
A lens is a thin curved piece of transparent material – glass, plastic, etc.
The two different types of lens include convex lens and concave lens.
The convex lens converges the light rays whereas the concave lens diverges the light rays.
Hence, a convex lens is also called an converging lens and the concave lens is also called as diverging lens.
