Arrange `mu_s, mu_k ` and `mu_r` in descending order.

Arrange the following numbers in descending order.

Arrange the following numbers in descending order.

The correct arrangement of colours in the descending order of wavelength is

Arrange coefficient of limitin friction (mu_1) ,coefficient of kinetic friction (mu_k) and coefficient of rolling ffriction (mu_r) in scending order.

Refractive indices of glass for lights of yellow,green and red colours are mu_y,mu_g and mu_r respectively.Rearrange these symbols in an increasing order of values.

A prism of refractive index mu_1 and another prism of refractive index mu_2 are struck together without a gap as shown in Fig.3.17. . The ngles of the prisms are shown . mu_1 and mu_2 depend on delta ,the wavelength of light according to mu_1=1.20 +(10.8 xx 10^4)/(delta^2) and mu_2 = 1.45 + (1.8 xx 10^4)/(delta^2) , where delta is in nm. Calculate the wavelength delta_0 for which rays incident at any angle on the interface BC pass through without bending at that interrface.

What is the relation between refractive indicises mu,mu_1 and mu_2 ,if the behaviour of light rays is as shown in Figs.2.69 and 2.70? .
