Question
For a light ray passing from air to water, according to Snell's law:
(n represents refractive index of the medium, θair is the angle of incidence and θwater is the angle of refraction)
Answer: Option A
:
A
According to Snell's law, for a light ray travelling from one medium to another, the ratio of sines of angle of incidence to the angle of refraction is a constant. This constant is the refractive index of medium 2 with respect to medium one.
Here,
nair sinθair = nwatersinθwater or ⇒SinθairSinθwater=nwaternair correctly represents Snell's law.
