Q
Q: If the frequency of a sound wave is doubled, what happens to its wavelength?
Solution:
Wavelength is inversely proportional to frequency; if frequency is doubled, wavelength halves.
Steps: 7
Show Steps
Step 1: Understand that sound waves have two important properties: frequency and wavelength.
Step 2: Frequency is how many times the wave cycles in one second, measured in Hertz (Hz).
Step 3: Wavelength is the distance between two consecutive points of the wave, like from one peak to the next.
Step 4: Learn that wavelength and frequency are related: when one increases, the other decreases.
Step 5: If the frequency of the sound wave is doubled, it means it cycles twice as fast.
Step 6: Since wavelength is inversely proportional to frequency, if frequency goes up, wavelength must go down.
Step 7: Therefore, if the frequency is doubled, the wavelength is halved.
