Monochromatic light hits a piece of glass.What happens to the wavelength in the glass as the index of refraction increases? A)decreases B)increases C)remains constant D)approaches 3 × 10⁸ m

Question

Quizplus · Accepted Answer

As the index of refraction increases, the speed of light in the medium decreases. This means that the wavelength of the light will also decrease according to the formula λ=nλ0, where λ0 is the wavelength of the light in vacuum and n is the refractive index of the medium. Therefore, the correct answer is that the wavelength decreases (choice A).
