Q. Illustrate how do you find the refractive index of a liquid by using total internal reflection?
Answer:-
Using Snell's law
n (1) = (n (2) x sin angle (2)) / sin angle (1).
n (1) = The refractive index of the greatly optically dense medium.
n (2) = The refractive index of the fewer optically dense medium.
angle (1) = The critical angle of the two mediums.
angle (2) = 90 degrees ever since when light is at the critical angle it undergoes total internal reflection.s
Since sin 90= 1 this is able to be ignored resulting in n (1) = n (2) / sin angle (1)

A charge is said to be in equilibrium, if total force performing on it is zero. A operation of charges is said to be in equilibrium if every charge is independently is equilibrium.
The device which changes chemical energy into electrical energy is called as electric cell. Battery is a host of constant emf but not constant current.
