Question

15.
What will be the wave velocity if radar gives 54 waves per min and wavelength of the given wave is 10 m.
(A) 4 m/s
(B) 6 m/s
(C) 9 m/s
(D) 5 m/s​

Answer 1

Answer:

It is given in the problem that the wave velocity if the radar gives 54 waves per minute and wavelength of the given wave is 10 meter. f= 50 waves per 60 second. Put and f= 50 waves per minute in the above expression. Therefore, the wave velocity is 9 m/s .
