Questions & Step-by-Step Solutions
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.
