2
Q
Reflection of light
A
The bouncing of light off an object is called reflection
3
Q
Laws of reflection of light
A
Law 1: The incident ray, the normal at the point of incidence and the reflected ray all lie on the same plane
Law 2: The angle of incidence is equal to the angle of reflection
4
Q
Virtual Image
A
A virtual image is an image formed by the apparent intersection of rays
5
Q
Parallax
A
The apparent movement of one object relative to another due to the motion of the observer is called parallax. The object that is farthest away appears to move with the observer
