Answer 1

Answer:

Ray of light: The direction or path along which light energy travels in a medium is called a ray of light. It is represented by a straight line with an arrow marked on it. Beam of light: A group of light rays is called a beam of light. A beam of light may be parallel, convergent or divergent

When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The incident light ray which lands upon the surface is said to be reflected off the surface. The ray that bounces back is called the reflected ray. If a perpendicular were to be drawn on a reflecting surface, it would be called normal. The figure below shows the reflection of an incident beam on a plane mirror.

Here, the angle of incidence and angle of reflection are with respect to normal and the reflective surface.
