If ` mu=u^y` then find ` mu_(uy)`

R is the radius of curvature for both the surfaces of lens shown in figure. Refractive index mu_(1), mu_(2) and mu_(3) are indicated in the figure. Light rays are incident from the side of refractive index mu_(1) as shown. If f is focal length of lens then find f//R for mu_(1) = 1, mu_(2)= 1.5, mu_(3)= 2 . |{:(0,1,2,3,4,5,6,7,8,9):}|

If mu is the universal set and P is a subset of mu then what is P nn(P-mu)uu(mu-P) equal to

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 )

If cot [cot^(-1)((7)/(25))]=(1)/(mu), where mu in R. Then find [mu], where [*] denotes GIF

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?

Repeat the above problem, if instead of mu , we are given mu_(s) and mu_(k) ,where mu_(s) =0.6 and mu_(k) =0.4 .

The observer 'O' sees the distance AB as infinitely large. If refractive index of liquid is mu_(1) and that of glass is mu_(2) , then (mu_(1))/(mu_(2)) is : .

A carrier wave is modulated by n number of sine waves with modulation indices mu_(1),mu_(2),mu_(3)+ .... The total modulation index (mu) of the wave is
