c = (5/9)(F-32)
c = (5/9)(86-32) = 30 deg C
I do not know what you are using, perhaps:
V = 331.4 + .6 C
V = 331.4 + .6(30) = 349.4 m/s
d = 349.4 * 2.3 = 804 meters
period = 1/653
lambda = 349.4 * 1/653 = .535 meter
The air temperature on a certain day is 86 degrees F
A)Convert to Celsius?
B) Calculate the sound of speed in air?
C)When a 653Hz tornado siren is turned on, the sound takes 2.3s to reach an observer. How far is the observer from the main siren, and what is the wavelength of sound produced?
