3. What is the temperature if a 545-Hz sound wave has a wavelength of 0.651 m
KATRIN_1 [288]

Answer:

19.33°C

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
