A) 25.16m
B) 16.25m
C) 32.50m
D) 8.25m
Correct Answer: B
Solution :
Wavelength is defined as the distance between repeating units of a wave pattern. It is related to frequency and velocity as \[\text{Wavelength = }\frac{\text{velocity}}{\text{frequency}}\] Given, Time t = 1.67 min. = 100 s Frequency of wave is \[n=\frac{4000}{100}=40\,per\,\sec \] Wavelength of wave is \[\lambda =\frac{v}{n}=\frac{650}{40}=16.25\,m\]You need to login to perform this action.
