Question

State the fundamental laws on which ray optics is based

Answer 1

Answer:

1)a ray should pass from optical centre

2)a ray should pass from focus

3)a ray should be parallel to principal axis

Answer 2

Explanation:

We define a ray as the path along which light energy is transmitted from one point to another in an optical system. The basic laws of geometrical optics are the law of reflection and the law of refraction. If not being reflected or refracted, a light ray travels in a straight line.
