Question

a sound wave has frequency 320 hz and wavelength 0.25 m. how much distance will ot travel in 10 seconds ?​

Answer 1

Heya dear....❤

Here's ur answer :-

$<b><i><u> given -$
t = 10 sec
wavelength = 0.25 m
frequency = 320 hz

We know that,

Speed of sound = frequency × wavelength
And, sound = distance ÷ time

Finding speed of sound :-
speed = 320 × 0.25
speed = 80m/s

Finding distance :-
distance = speed × time
d = 80 × 10
d = 800m

Hence, wave travels a distance of 800m

Hope it helps ✔

Answer 2

Explanation:

Speed of sound = frequency × wavelength

And, sound = distance ÷ time

Finding speed of sound :-

speed = 320 × 0.25

speed = 80m/s

Finding distance :-

distance = speed × time

d = 80 × 10

d = 800m
