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.

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? .
