If the wavelength of light used in a diffraction grating is increased, what happens to the angular separation of the fringes? (2023)

Step 1: Understand what a diffraction grating is. It is a tool that spreads light into its different colors (wavelengths).
Step 2: Know that the wavelength (λ) of light is the distance between two peaks of the light wave.
Step 3: Learn that angular separation (θ) is the angle between two bright spots (fringes) created by the diffraction grating.
Step 4: Remember the relationship: as the wavelength (λ) increases, the angular separation (θ) also increases.
Step 5: Conclude that if the wavelength of light used in the diffraction grating is increased, the angular separation of the fringes will also increase.

Diffraction Grating – A device that disperses light into its component wavelengths, creating a pattern of bright and dark fringes.
Angular Separation – The angle between two adjacent fringes in a diffraction pattern, which is influenced by the wavelength of light.
Wavelength Dependence – The relationship between the wavelength of light and the resulting angular separation of fringes in diffraction patterns.
