Question

Two sound waves in air have thier wave length in the ratio2:5. find their frequency ratio

Answer 1

Answer:

Explanation:

Frequency is reciprocally proportional to wavelength. If the ratio of the two sounds' wavelengths is 2:5 , then the ratio of their frequencies is 5:2 .

Answer 2

Answer:

Since wavelength = C/f where c is speed of wave in vacuum and f is the frequency of the wave, we get that wavelength is inversely proportional to frequency. Now the ratio of wavelength given is 2:5 so using the inverse proportionality we get ratio of frequency as 5:2. Thanks for the A2A :)
