Question: What is the effect of increasing the wavelength of light on the angle of refraction when it passes from air into glass? (2023)

Options:

Correct Answer: Decreases

Exam Year: 2023

Solution:

Increasing the wavelength of light decreases the angle of refraction when passing from air into glass due to the dispersion of light.

Step 1: Understand what wavelength of light means. Wavelength is the distance between two peaks of a light wave.
Step 2: Know that when light travels from one medium (like air) to another (like glass), it bends. This bending is called refraction.
Step 3: Learn about the angle of refraction. This is the angle at which light bends when it enters a new medium.
Step 4: Recognize that different wavelengths of light can bend differently. Shorter wavelengths (like blue light) bend more than longer wavelengths (like red light).
Step 5: Realize that increasing the wavelength means the light is becoming 'redder' or moving towards the longer wavelength end of the spectrum.
Step 6: Understand that as the wavelength increases, the angle of refraction decreases. This means the light bends less when it enters the glass.
Step 7: Conclude that increasing the wavelength of light results in a smaller angle of refraction when passing from air into glass.
