Final answer:
The wavelength of a wave with a speed of 1100 feet/sec and a frequency of 440 Hz is 2.5 feet. This is calculated using the wave equation, with the wavelength being the wave speed divided by the frequency.
Step-by-step explanation:
To find the wavelength of a wave when the speed and the frequency are known, you can use the formula for the wave equation:
v = f × λ
Where:
- v is the wave speed
- f is the frequency
- λ (lambda) is the wavelength
Rearrange the equation to solve for the wavelength λ:
λ = v / f
For this question:
- Speed, v = 1100 feet/sec
- Frequency, f = 440 Hz
Substituting the values into the equation:
λ = 1100 feet/sec / 440 Hz = 2.5 feet
So, the wavelength is 2.5 feet.
