(sec mu-tan mu)^(2)=((1-sin mu))/((1+sin mu))

The refractive indices of a medium for two light waves are mu_(1) and mu_(2) . If mu_(1) gt mu_(2) , then which wave will move faster in the medium?

Assertion : A double convex lens (mu=1.5) has focal length 10 cm . When the lens is immersed in water (mu=4//3) its focal length becomes 40 cm . Reason : (1)/(f)=(mu_(1)-mu_(m))/(mu_(m))((1)/(R_(1))-(1)/(R_(2)))

The refractive indices of three media 1,2 and 3 and mu_(1),mu_(2) and mu_(3) respectively (mu_(1) gt mu_(2) gt mu_(3)) . Which of the following statements are correct?

int sin(101x)sin^(99)xdx=(sin(100x)(sin x)^(lambda))/(mu) then (lambda)/(mu)

Light enters a prism of angle A at a grazing incidence to emerge at an angle theta with the normal. Show that, mu for the material of a prism is given by mu = [1+((sin theta + cos A)/(sin A))^(2)]^((1)/(2))

Prove that (-mu_1)/(u)+(mu_2)/(v) = (mu_2 - mu_1)/( R) when refraction occurs from rarer to denser medium at a concave spherical refracting surface.

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 : .
