Question

give an example for a curved surface and a plain surface to observe refraction

Answer 1

Answer:

For every point in curved surface there. is a normal on it. When the ray falls on any. point it makes some angle with normal and following law of reflection the reflected ray make equal angle with normal as incident ray goes backward . that's how light refracted at curved ssurfaceplz mark my answer as brainliest

Answer 2

Answer:

parallelogram is the example of this
