Question

A glass prism has a refractive index sensitivity of the eye is 1.5 and the refracting angle is 90° if array falls on it at an angle of incidence of 30 degree then the angle of emergence is

Answer 1

angle of incidence = angle of emergence

Answer 2

Answer:

Explanation:

When an object falls freely towards the ground, its potential energy decreases and kinetic energy increases.

As the object touches the ground, all its potential energy gets converted into kinetic energy.

As the object hits the hard ground, all its kinetic energy gets converted into heat energy and sound energy.

It can also deform the ground depending upon the nature of the ground and the amount of kinetic energy possessed by the object.
