Want this question answered?
Reflection.
when arrival of a beam of light at a surface
It is called a beam.
Whats the question?
Yes, this is called the photoelectric effect. Discovered my Einstein.
Reflection.
when arrival of a beam of light at a surface
A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

Reflectivity isn't a property of light, it's a property of the surface that reflects the light. It is the proportion of the energy in an incoming light beam which when it hits the surface is reflected rather than absorbed.
Whats the question?
It is the angle of incidence.
The beams of the Sun has reached the Earth's surface.
A ray.
Yes, this is called the photoelectric effect. Discovered my Einstein.
When a beam of light strikes a reflective surface it reflects, angle of incidence = angle of reflection
