A prism of refractive index
2 has a refracting angle 60 degree. At what a ray must be incident on it so that it
suffers minimum deviation ?
An equilateral prism is placed in the minimum deviation position .If the angle of incidence is 60 degree , the
angle of deviation is :
A prism of angle 6 degree produces a deviation of 3.5 dgree .The refractive index of the prism is :
The angle of deviation is maximum for :
A ray of light is incident on one face of prism of refracting angle 30 degree at an angle of incidence 60 dgree.
If the ray emerges along the normal to the second face , what is the refractive index of the prism ?
A ray is incident normally on one face of a prism of refractive 1.33 , and the emergent ray grazes the opposite
face .What is the angle of the prism ?
A peice of glass is heated till it glows in dark . The colour of the peice becomes :
if d is the of a normally falling ray of athin prism of angle A and w is the dispersive power of the prism then :
A prism of angle 6 degree and refractive index 1.5 is placed in water of refractive index 1.33.the deviatin produced is;
The difference between the angle of minimum deviation for violet and red for a prism is 2 degre.if the deviation
for violet is 48 degree the dispersive power is :
