Question

HØLa !!



From above diagram alongside calculate

▶velocity P and Q

▶ Frequency of P when frequency of Q is 512 Hz.
Assume that the both wave are travelling in same medium



Good luck ✌


thanks ☺

Answer 1

L=λ=wavelenght

Lp=8m

Lq=4m

Ap=8m

Aq=4m

as medium is same so frequency remains same

v=fL

vp=Lp=8m/s

vq=Lq=4m/s

as i said frequency depends on medium

so frequency of P is also 512 HZ

hope this helps

Answer 2

$\underline\bold{Answer}$


Velocity of p = 8m/s

Velocity of q = 4 m/s
