Question

a sound has a constant speed 320 M per second if frequency is 8 hertz find the wavelength and time period​

Answer 1

Answer:

Explanation:

Speed= Wavelength*Frequency

320= Wavelength*8

Wavelength= 40m

$Time period=\frac{1}{Frequency}$

$Time period= \frac{1}{8}$

Answer 2

Hey!!

Given ,

Speed (v) = 320 m/s

Frequency (ν) = 8 hz

Wavelength (λ) = ?

Time period ( T) = ?

We know that,

v = νλ

v / ν = λ

320 / 8 = λ

λ = 40 m

T = λ / ν

T = 40/5

T = 8 seconds.
