FIRST AND CORRECT ANSWER WILL BE MARKED AS BRAINLIEST. ​

Answer 1

Answer:

1. angle of incidence is always equal to angle of reflection.
2. it should give the best reflection. it should not absorb any light.it should not transmit any light
3. when light rays strikes a polished surfaces,the light rays bounces back in the same direction in which it was incidence

Answer 2

Answer:

1)

• The incident ray, the reflected ray and the normal are all in the same plane.
• The incident ray and the reflected ray are on the opposite sides of the normal.
• The angle of incident is always equal to the angle of reflection

2) Reflectivity ,Surface quality,Transmissivity.

3) Regular reflection occurs when a parallel beam of light is reflected parallel to each other from a smooth surface

4) Irregular reflection occurs when a parallel beam of light is scattered in many directions after reflecting from a rough surface.

5) The throwing back by a body or surface of light, heat, or sound without absorbing it.When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light.
