Answer:
The angle at which the light emerges from the opposite face of the prism with respect to the original incident beam is 53.3°.
Explanation:
Given that,
Angle
Refractive index n=1.5
For the refraction at the first surface
We need to calculate the angle
Using formula of refraction
Put the value into the formula
We need to calculate the angle on incidence at the second surface
Put the value into the formula
For the refraction at the second surface,
We need to calculate the angle at which the light emerges from the opposite face of the prism with respect to the original incident beam direction
Using formula of refraction
Put the value into the formula
The angle is 53.3° from the original
Hence, The angle at which the light emerges from the opposite face of the prism with respect to the original incident beam is 53.3°.
