Three thin prisms are combined as shown in figure . The refractive indices of the crown glass for red , yellow and violet rays are mu_r,mu_yand mu_v respectively and those for the flint glass are mu_r',mu_y'and mu_v' respectively . Find the ratio (A')/A for which , there is no net angular dispersion (A and A' are respective deviations )

In the figure shown mu_(1),mu_(2),mu_(3),mu_(4) and mu_(5) are the refractive indices of the mediums 1,2,3,4 and 5 respectively. Consider the following: (1) mu_(1)=mu_(2) (2) mu_(3)=mu_(4)=mu_(5) (3) mu_(2) lt mu_(3) (4) mu_(4)gt mu_(5) Which of the above are correct?

The equation of refraction at a spherical surface is mu_2/v-mu_1/u=(mu_2-mu_1)/R Taking R=oo , show that this equation leads to the equation (Real depth)/(Apparent depth)=mu_2/mu_1 for fraction at a plane surface.

Consider the situation as shown in the figure. If mu_(1) is the friction coefficient between block A and incline and mu_(2) is the friction coefficient between block B and incline. Find the acceleration of block A if (a) mu_(1) = (1)/(5) , mu_(2) =(2)/(5) and (b) mu_(1) = (2)/(5) , mu_(2) = (1)/(5) .
