Question: What happens to the diffraction pattern when the distance to the screen is increased?

Options:

Correct Answer: Fringe width increases

Solution:

Increasing the distance to the screen results in an increase in fringe width in the diffraction pattern.

What happens to the diffraction pattern when the distance to the screen is increased?

Step 1: Understand what a diffraction pattern is. It is a pattern of light and dark bands created when light waves spread out after passing through a small opening or around an obstacle.
Step 2: Know that the distance from the opening (or obstacle) to the screen where the pattern is observed can affect the pattern.
Step 3: When you increase the distance to the screen, the light waves have more space to spread out.
Step 4: As the light waves spread out more, the distance between the bright and dark bands (called fringe width) increases.
Step 5: Therefore, increasing the distance to the screen makes the fringe width larger, resulting in a wider diffraction pattern.

Diffraction Patterns – The behavior of waves as they encounter obstacles or openings, leading to interference patterns.
Fringe Width – The distance between adjacent bright or dark fringes in a diffraction pattern, which is affected by the distance to the screen.
