Question

how do you appreciate the role of fermat principle in drawing Ray diagrams

Answer 1

Fermat’s principle says that light selects a shortest path to travel. This is the basic
reason for the straight line propagation of light using this principle, we can draw ray
diagram to trace the image formed by mirrors to understand reflection and refraction.

Answer 2

• fermet's principle is the principle that the path taken between two points by a light ray is the path transverse in least time
• it used to describe the properties of light rays of reflected off mirrors
• refraction through different mediums
• undergoing total internal reflection
