Question

For the same angle of incidence in media P, Q and R, the angles of refraction
are 45°, 35º and 15° respectively. In which medium will the velocity of light
minimum? Give reason.​

Answer 1

Answer:

from snell's law refractive index=sini/sinr

speed of light is faster in rarer medium so from the medium are the value of refractive index will be large and speed of light medium the refractive index is small in p medium hence is p medium so the speed of light maximum
