Question

What is the speed of sound at 21 C? For a frequency of 3 kHz, how large do you expect the wavelength to be?

477.5 m/s (express your answer in integral form) 0.15915 (express your answer with 2 decimal place)

Answer 1

0.11m

Step-by-step explanation:

The speed of sound at 21°C is approximately 343 m/s.

To calculate the wavelength for a frequency of 3 kHz, we can use the formula:

wavelength = speed of sound / frequency

Plugging in the values we have:

wavelength = 343 m/s / 3000 Hz = 0.1143 meters

Rounding to two decimal places, we get a wavelength of 0.11 meters or 0.11 m.
