Question

Figure shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is : 45° 45° Medium B 30° Medium A 60° Fig 4.77​

Answer 1

Answer:

Correct

Answer

The Snell's law simply relates angles i and r to the refraction indices of the two media A and B. Therefore, refractive index of medium B relative to medium A is:

n=

sinr
