Q: What happens to the diffraction pattern when the distance to the screen is increased?
Solution: Increasing the distance to the screen results in an increase in fringe width in the diffraction pattern.
Steps: 5
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.
