Answer:

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
