When a ray of light enters into another optical medium, its wavelength and velocity change. The material in which wavelength and velocity decrease maximum, when the ray is travelling through air is :
The correct option is B diamond
Explanations for the correct answer:
Option B is correct.
When a ray of light enters another optical medium, its wavelength and velocity change. The material in which wavelength and velocity decrease maximum, when the ray is traveling through air is diamond. Because when the light travels from a rarer medium to the denser medium the speed of light is decreased.
Explanations for the Incorrect answer:
Option A: alcohol
Alcohol is less denser than diamond because the refractive index of alcohol is less than diamond.
Option C: Glass
Glass is less denser than diamond because the refractive index of glass is less than diamond.
Option D: water
Water is less denser than diamond because the refractive index of water is less than diamond.
Hence the answer is Diamond.
