Q1
If the wavelength of light used in a diffraction experiment is halved, what happens to the position of the minima?
They move closer together
They move further apart
They remain unchanged
They disappear
Halving the wavelength causes the minima to move closer together, as the angle for minima is directly proportional to the wavelength.

Q: If the wavelength of light used in a diffraction experiment is halved, what happens to the position of the minima?
Solution: Halving the wavelength causes the minima to move closer together, as the angle for minima is directly proportional to the wavelength.
Steps: 6
Step 1: Understand what a diffraction experiment is. It involves light passing through a narrow opening and creating a pattern of light and dark areas called minima and maxima.
Step 2: Know that the wavelength of light is the distance between two consecutive peaks of the light wave.
Step 3: Recognize that the position of the minima in a diffraction pattern is related to the wavelength of the light used.
Step 4: Remember that if the wavelength is halved, it means the distance between the peaks of the light wave is shorter.
Step 5: Understand that when the wavelength decreases, the angle at which the minima occur also decreases, causing the minima to move closer together.
Step 6: Conclude that halving the wavelength results in the minima being closer together in the diffraction pattern.
