Answer:
Option C is correct
Explanation:
Wavelength of the sound waves varies inversely with respect to frequency which means that if frequency increases wavelength will decrease and if frequency decreases wavelength increase.
Mathematically this relation can be represented as -
[tex]W \alpha \frac{1}{f}[/tex]
Where W represents the wavelength and f represents the frequency
When frequency is constant, wavelength exhibit direct proportionality relationship with speed.
