Q36. When a ray of light enters a glass slab from air:
(a) its wavelength decreases
(b) its waveleng

Q: What is the correct answer for CUET UG Physics Q36?

The correct answer is a. When a ray of light passes from one medium to another, its frequency (f) remains constant because frequency is an intrinsic property of the light source. However, the speed of light (v) changes depending on the refractive index of the medium. Light travels slower in denser media like glass than in air. Since the relationship between speed, frequency, and wavelength is v = fλ, and v decreases while

FirstInTest · Accepted Answer

When a ray of light passes from one medium to another, its frequency (f) remains constant because frequency is an intrinsic property of the light source. However, the speed of light (v) changes depending on the refractive index of the medium. Light travels slower in denser media like glass than in air. Since the relationship between speed, frequency, and wavelength is v = fλ, and v decreases while f remains constant, the wavelength (λ) must decrease.

Answer

its wavelength decreases

Answer

its wavelength increases

Answer

its frequency increases

Answer

neither its wavelength nor its frequency changes
