Question

3. What is the temperature if a 545-Hz sound wave has a wavelength of 0.651 m

Answer 1

19.33°C

Step-by-step explanation:

To find the value of T you use the following formula:

`v=343+0.61T`

v: speed of sound

To calculate v you use:

`v=\lambda f`

λ: wavelength = 0.651m

f: = 545Hz

by replacing :

`v=(0.651m)(545s^(-1))=354.79m/s`

Finally, by replacing in the first formula you obtain:

`354.79=343+0.61T\\\\T=19.33\°C`

T = 19.33°C
