Question

a light wave of wavelength 7400 A passes through a glass slab. what will be the wavelength of light wave in the glass ??​

Answer 1

ᾰṧ-ṧᾰℓᾰՊ ᾰℓ!кṳՊ!!!

the wavelength of light wave in the glass is given as :-

n = 1.5

according to formula :-

lemda ' = lemda / n

= 7400/1.5

= 4933.3 A°

Answer 2

$\huge\mathfrak\red{Hello}$

Wavelength of light in glass = 1.5

according to given formula :---

refractive index of Glass = wavelength of light in air / wavelength of light in medium X

1.5 =7400A/ wavelength of light in glass

therefore, wavelength of light in glass =4,933.34 Angstrom.
