Light enters an equilateral triangle prism in a direction parallel to one side. the prism is made of glass with an index of refraction of 1.52. what is the angle between the incoming ray and the ray that leaves the prism on the other side?

31.2 degree

Explanation:

Angle of prism, A = 60 degree

refractive index, μ = 1.52

The angle between the incident ray and the emergent ray is called angle of deviation δ.

The angle between the ange of deviation and the refractive index is

δ = (μ - 1) A

δ = (1.52 - 1) x 60

δ = 31.2 degree

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
