Question

A source of frequency 500 Hz emits waves of wavelength 0.2m.How long does it take to travel 300 m?

Answer 1

Hey mate,

The answer to your question is 3 seconds.

SOLUTION:

Wavelength=0.2m

Frequency=500Hertz

Distance=300 m

Using formula

Velocity=V =frequency x wavelength

V=500*0.2

V=100 m/s

Time =t =distance/velocity

t = 300m / 100 ms^-1

t =3 seconds

Answer 2

Answer:

3 seconds

Explanation:

GIVEN

Frequency = 500 hz

wave length = 0.20 m and Distance D = 300m

so velocity v = 500× 0.20 = 100 m/ sec

Time taken = D/ v = 300/100 = 3 sec
