Question: What is the relationship between the wavelength of light and the angle of diffraction in a single-slit experiment? (2023)

Options:

Correct Answer: Inversely proportional

Exam Year: 2023

Solution:

The angle of diffraction is inversely proportional to the wavelength; as the wavelength increases, the angle of diffraction decreases.

Step 1: Understand what wavelength is. Wavelength is the distance between two peaks of a wave of light.
Step 2: Learn about diffraction. Diffraction is the bending of light waves when they pass through a narrow opening, like a slit.
Step 3: In a single-slit experiment, light passes through one slit and creates a pattern of light and dark areas on a screen.
Step 4: The angle of diffraction is the angle at which the light waves spread out after passing through the slit.
Step 5: Know that as the wavelength of light increases (meaning the waves are longer), the angle at which the light spreads out (the angle of diffraction) becomes smaller.
Step 6: Conversely, if the wavelength decreases (the waves are shorter), the angle of diffraction increases.
Step 7: This means that the angle of diffraction is inversely proportional to the wavelength: longer wavelengths lead to smaller angles, and shorter wavelengths lead to larger angles.
