Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 20.
Calculation:
The formula that relates the speed of a wave (v), its frequency (f) and its wavelength (λ) is:
v = f × λ
Where:
v is speed of the wave
f is frequency of the wave
λ wavelength
Let's rearrange the formula to solve for wavelength (λ):
\(λ = {{v} \over f}\)
Given:
v = 340 m/s
f = 1700 Hz
Substitute the values into the formula:
\(λ = {{340} \over 1700}\)
λ = 0.2 m = 20 cm
Thus, If the speed of a sound wave is 340 m/s and its frequency is 1700 HZ, then wavelength (λ) for this wave in cm will be 20.
