Question: In a diffraction pattern, if the distance between the slits is decreased, what happens to the central maximum? (2022)

Options:

Correct Answer: It becomes wider

Exam Year: 2022

Solution:

Decreasing the distance between the slits increases the diffraction effect, causing the central maximum to become wider.

In a diffraction pattern, if the distance between the slits is decreased, what happens to the central maximum? (2022)

In a diffraction pattern, if the distance between the slits is decreased, what happens to the central maximum? (2022)

Step 1: Understand what a diffraction pattern is. It is a pattern created when waves, like light, pass through slits and spread out.
Step 2: Know that the central maximum is the brightest part in the middle of the diffraction pattern.
Step 3: Recognize that the distance between the slits affects how the waves interfere with each other.
Step 4: When the distance between the slits is decreased, the waves spread out more.
Step 5: This spreading out of the waves causes the central maximum to become wider.
Step 6: Therefore, decreasing the distance between the slits results in a wider central maximum in the diffraction pattern.

Diffraction and Interference – The phenomenon where waves spread out after passing through a narrow aperture or around obstacles, affecting the pattern of light observed.
Slit Separation – The distance between the slits in a double-slit experiment, which influences the spacing and width of the interference pattern.
Central Maximum – The brightest point in the diffraction pattern, located at the center, which is affected by the slit separation.
