The frequency of a sound wave can be calculated using the formula:
Frequency = Speed of sound / Wavelength
The speed of sound in air at 20°C is approximately 343 meters per second. To convert the wavelength from centimeters to meters, we divide it by 100.
Given that the wavelength is 95 cm (or 0.95 meters), and the speed of sound is 343 meters per second, we can calculate the frequency as follows:
Frequency = 343 m/s / 0.95 m = 360.53 Hz
Therefore, the frequency of the sound wave with a wavelength of 95 cm at 20°C is approximately 360.53 Hz.
