Question: If the wavelength of light used in a diffraction experiment is halved, what happens to the position of the first diffraction minimum?

Options:

Correct Answer: It moves closer to the center

Solution:

Halving the wavelength results in the first minimum moving closer to the center, as the position of minima is directly related to the wavelength.

If the wavelength of light used in a diffraction experiment is halved, what happens to the position of the first diffraction minimum?

Correct Answer: The first minimum moves closer to the center.

Step 1: Understand what a diffraction experiment is. It involves light passing through a small opening or around an obstacle, creating a pattern of light and dark areas.
Step 2: Know that the position of the diffraction minima (dark spots) depends on the wavelength of the light used.
Step 3: Recognize that if the wavelength is halved, it means the light is now shorter in wavelength.
Step 4: Realize that shorter wavelengths lead to the first minimum moving closer to the center of the diffraction pattern.
Step 5: Conclude that halving the wavelength causes the first diffraction minimum to shift inward, towards the center.

Diffraction and Wavelength Relationship – The position of diffraction minima is inversely related to the wavelength of light used in the experiment.
