Question: What happens to the diffraction pattern when the slit width is decreased?

Options:

Correct Answer: Pattern becomes wider

Solution:

Decreasing the slit width increases the diffraction angle, causing the diffraction pattern to become wider.

What happens to the diffraction pattern when the slit width is decreased?

Step 1: Understand what diffraction is. Diffraction is the bending of waves around obstacles or through openings.
Step 2: Know that a slit is an opening through which waves (like light) pass.
Step 3: Recognize that the width of the slit affects how the waves spread out after passing through it.
Step 4: When the slit width is decreased, the waves spread out more after passing through the slit.
Step 5: This spreading out of waves increases the angle at which the waves diffract.
Step 6: As a result, the diffraction pattern (the pattern of light and dark areas created) becomes wider.

Diffraction – The bending of waves around obstacles and openings, which is influenced by the size of the slit relative to the wavelength of the light.
Slit Width and Diffraction Angle – As the slit width decreases, the diffraction angle increases, leading to a wider diffraction pattern.
