The diagram above illustrates a wave setup between two fixed ends 4.0m apart. If the speed of the wave is 1.0ms−1, its wavelength and frequency respectively are
1m; 0.25Hz
2m; 0.25Hz
2m; 0.50Hz
4m; 0.50Hz
Correct answer is C
For the 4th harmonic, L=2λ
4m=2λ⟹λ=4m2
=2m
Recall, v=fλ
1=f×2⟹f=12
= 0.50Hz
