Question: If the wavelength of light is halved, what happens to the frequency of the light?

Options:

Correct Answer: It doubles

Solution:

Frequency (f) is inversely proportional to wavelength (λ). If λ is halved, f doubles.

If the wavelength of light is halved, what happens to the frequency of the light?

If the wavelength of light is halved, what happens to the frequency of the light?

Step 1: Understand that wavelength (λ) is the distance between two peaks of a wave.
Step 2: Know that frequency (f) is how many waves pass a point in one second.
Step 3: Remember the relationship: frequency (f) is inversely proportional to wavelength (λ). This means if one goes up, the other goes down.
Step 4: If the wavelength (λ) is halved, it means it becomes shorter.
Step 5: Since frequency (f) and wavelength (λ) are inversely related, if the wavelength is halved, the frequency must increase.
Step 6: Specifically, if the wavelength is halved, the frequency doubles.
