DAILY DOUBLE: A wave is observed to have a speed (v) of 30 meters per second and a wavelength (𝜆) of 5 meters. If the wavelength is suddenly doubled to 10 meters, what must happen to the wave's frequency (f), assuming the wave speed remains constant?
A. The frequency will also double (multiply by 2).
B. The frequency will decrease by half (divide by 2).
C. The frequency will remain exactly the same.
D. The frequency will increase fourfold (multiply by 4).
Correct Choice: B. The frequency will decrease by half (divide by 2).
Explanation
This question uses the same wave speed equation, v = f \𝝺, or rearranged to solve for frequency: f = v / 𝝺.
Initial State:
v = 30m/s 𝝺= 5m f = v / 𝝺 = {30m/s / 5m} = f is Hz
New State (Wavelength Doubled):
v = 30 m/s (constant)
New 𝝺 = 10 m} (doubled from 5 m)
New f = v / 𝝺 = 30m/s / 10 m} = 3 Hz
The original frequency was 6 Hz, and the new frequency is 3 Hz. Since the wavelength was doubled (multiplied by 2) and the speed was constant, the frequency must be halved (divided by 2) to maintain the equality v = f \𝝺.
