Question

please please please solve it it's very very urgent tomorrow is my exam of physics

Answer 1

given

frequency=500hz

wavelength=0.66m

velocity =?

from the relation between velocity time and wavelength

we get

v = n× lambda

v= 500 ×0.66

= 330 m per second

Answer 2

Given :
Frequency (f)=500Hz
Wavelength = 0.66m
velocity (v)= to be calculated
putting the formula;
velocity = frequency *wavelength
= 330.00m/s
