Can you ever have a situation in which a light ray goes undeviated through a prism ?

Can you cite a situation where no force acts on a body.

A crown glass prism of angle 5^@ is to be combined with a flint glass prism in such a way that the mean ray passes undeviated. Find (a) the angle of the flint glass prism needed and (b) the angular dispersion produced by the combination when white light goes through it. Refractive indices for red, yellow and viloet light are 1.514, 1.517 and 1.523 respectively for crown glass and 1.613 1.620 and 1.632 for flint glass.

Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?

suggest a situation in which an obiect is accelerated and have constant speed.

When sunlight passes through glass prism which light deviates the least ?

Write about two everyday situations that tell you that light travels in a straight line.

Write about two everyday situations that tell you that light travels in a straight line.

The angle of incidence for a ray of light of a refracting surface of at prism is 45^@ . The angle of prism is 60^@ . If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are

A thin prism of angle 6.0^@, omega'=0.07 and mu_y'=1.50 is combined with another thin prism having omega = 0.08 and mu_y = 1.60 . The combination produces no deviation in the mean ray. (a) Find the angle of the second prism. (b) Find the net angular dispersion produced by the combination when a beam of white light passes through it. (c) If the prisms are similarly directed, what will be the deviation in the mean ray ? (d) Find the angular dispersion in the situation described in (c).
