Question

give the answer in very short ​please because this is very short question don't write long answer​

Answer 1

Answer:

In general, the angle of incidence is equal to the angle of reflection (Snell's Law). Thus, for a smooth horizontal surface, sharp images are formed. If the surface detracts from flatness then this breaks up the sharp image of a smooth, calm surface because the reflected light is no longer in the same plane.

Answer 2

Waves of light are represented by arrows called rays. Rays that strike the surface are referred to as incident rays, and rays that reflect off the surface are known as reflected rays. In regular reflection, all the rays are reflected in the same direction.  This is why diffuse reflection forms, at best, a blurry image.

can`t say the answer in short
