Question: If the wavelength of a wave is halved, what happens to its frequency?
Options:
It remains the same
It doubles
It halves
It quadruples
Correct Answer: It doubles
Solution:
Frequency is inversely proportional to wavelength. If the wavelength is halved, the frequency doubles.

Questions & Step-by-Step Solutions
If the wavelength of a wave is halved, what happens to its frequency?
Correct Answer: Frequency doubles
Step 1: Understand what wavelength and frequency are. Wavelength is the distance between two peaks of a wave, and frequency is how many waves pass a point in one second.
Step 2: Learn the relationship between wavelength and frequency. They are inversely proportional, which means if one goes up, the other goes down.
Step 3: If the wavelength is halved, it means the distance between the peaks is shorter.
Step 4: Since the wavelength is shorter, more waves can fit in the same amount of time.
Step 5: Therefore, if the wavelength is halved, the frequency must double to accommodate the increased number of waves.
