hey user !!!!!
given ::-
wave speed = 25m/s.
frequency= 512 HZ.
Theirfore,, wave length = wave speed ÷frequency
= 25÷512= 0.048828125.
now wave length = 0.04 m(approx)
now frequency = wave speed ÷ wave length
= 25m/s ÷ 0.04= 625 HZ..
Theirfore,, The requried frequency = 625 HZ.
Hope it helps u.. plz follow me for more answers..
