To determine the frequency of a sound wave, we can use the formula:
v = λ * f
where: v is the velocity of sound in the medium, λ (lambda) is the wavelength of the sound wave, and f is the frequency of the sound wave.
The velocity of sound in air at 20°C is approximately 343 meters per second.
First, let's convert the wavelength from centimeters to meters: 95 cm = 0.95 meters
Now, we can rearrange the formula and solve for the frequency:
f = v / λ
f = 343 m/s / 0.95 m
f ≈ 360.53 Hz
Therefore, the frequency of the sound wave with a wavelength of 95 cm at 20°C is approximately 360.53 Hz.
