Answer 1

Answer:

1  an instrument containing loose bits of colored material between two flat plates and two plane mirrors so placed that changes of position of the bits of material are reflected in an endless variety of patterns.

2 The phenomenon of left side appearing right side and. right side appearing left side on reflection in a plane mirror is called. lateral inversion.

3.when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence.

4.When a parallel light beam reaches a rough surface, the light rays are reflected in various directions, or the light rays are dispersed, termed as irregular reflection.
