If deviation by a prism with small prism angle with refractive index 1.6 is 3.6^@ , then prism angle is ….....

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^(@) . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^(@) . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light

A direct-vision prism is made out of three prisms, each with a refracting angle of phi=60^(@) , attached to each other as shown in Figure. Light of a certain wavelength is incident on the first prism. The angle of incidence is 30^(@) and the ray leaves the third prism parallel to the direction of incidence. The refractive index of the glass of the first and third prisms, is 1.5. Find the refractive index of the material of the middle prism. (sqrt(6)=2.45)

A combination of two prisms, one of flint and other of crown glass produces dispersion without deviation. The angle of flint glass prism is 15^@ . Calculate the angle of crown glass prism and angular separation of red and violet rays on emergence from the spectroscope. ( mu for crown glass = 1.52, mu for flint glass = 1.65, omega for crown glass = 0.02, omega for flint glass = 0.03 ).

A right angled prism of refractive index mu_(1) is placed in a rectangular block of refractive index mu_(2) , which is surrounded by a medium of refractive index mu_(3) ,as shown in the figure . A ray of light 'e' enters the rectangular block at normal incidence . depending upon the relationship between mu_(1) , mu_(2) "and" mu_(3) , it takes one of the four possible paths 'ef' , 'eg' , 'eh' or 'ef' Match the paths in List I with conditions of refractive indices in List II and select the correct answer using the codes given below the lists: {:("List" I , "List" II) , ( P. e rarr f , 1. mu_(1)gt sqrt(2mu_(2))) , ( Q. e rarr g , 2. mu_(2) gt mu_(1) "and" mu_(2) gt mu_(3)), ( R. e rarr f , 3. mu_(1) = mu_(2)), ( S. e rarr f , 4. mu_(2) lt mu_(1) lt sqrt(2mu_(2)) "and" mu_(2) gt mu_(3)):} Codes : {:( P , Q , R , S) , ((A) 2 , 3 , 1 , 4), ((B) 1 , 2 , 4 , 3) , ((C) 4 , 1 , 2 , 3) , ((D) 2, 3 , 4 , 1):}

For a glass prism (mu = sqrt(3)) , the angle of minimum deviation is equal to the angle of the prism . Find the angle of the prism .

Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is mu , a ray, incident at an angle theta , on the face AB would get transmitted through the face AC pf the prism provided.

A prism of refractive index mu_1 = 1.42 and prism angle 10° is arranged with another prism of refractive index mu_2 = 1.7. If this combination gives the dispersion without deviation, then what should be the prism angle of second prism?
