A prism `(mu=1.5)` has the refracting angle of `30^(@)` The deviation of a monochromatic ray incident normally on its one surface will be `(sin 48^(@) 36 = 0.75)`

A

`18^@ 36^'`

B

`20^@ 30^(')`

C

`18^@`

D

`22^@1^(')`

Text Solution

Verified by Experts

The correct Answer is:
1
By using ` mu=(sini)/(sinA) implies 1.5=(sini)/(sin30^@) implies 0.75 implies i=48^@36^(.)`
