Questions & Step-by-Step Solutions
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.
