Question: In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe pattern?

Options:

Correct Answer: Fringe width increases

Solution:

Increasing the distance to the screen increases the fringe width, as fringe width is proportional to the distance from the slits.

In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe pattern?

In a double-slit experiment, if the distance to the screen is increased, what happens to the fringe pattern?

Step 1: Understand what a double-slit experiment is. It involves shining light through two narrow slits to create a pattern of light and dark stripes (fringes) on a screen.
Step 2: Know that the distance from the slits to the screen is important. This distance affects how the light waves spread out.
Step 3: Realize that when you increase the distance to the screen, the light waves have more space to spread out.
Step 4: Understand that as the light waves spread out more, the distance between the bright and dark stripes (fringe width) also increases.
Step 5: Conclude that increasing the distance to the screen results in wider fringes in the pattern.

Fringe Width – The fringe width in a double-slit experiment is the distance between adjacent bright or dark fringes, which is affected by the distance from the slits to the screen.
Double-Slit Experiment – A fundamental experiment in wave optics demonstrating the wave nature of light through the interference pattern created by two coherent light sources.
Interference Pattern – The pattern of alternating bright and dark fringes resulting from the constructive and destructive interference of light waves.
