Light And Optics Physics Test

Angle of incidence -

✅ The angle between a ray that strikes a surface and the normal to that

surface at the point of contact

Angle of reflection -

✅ The angle formed by the line normal to a surface and the direction in which

a reflected ray moves

Critical angle -

Index of refraction -

✅ The ratio of the speed of light in a vacuum to it's speed in a given

transparent medium

Real image -

✅ An image formed when rays of light actually intersect at a single point

Reflection -

✅ The turning back of an electromagnetic wave at the surface of a substance

Refraction -

✅ The bending of a wave disturbance as it passes at an angle from one

medium to another
