Question

On a cold day, the speed of sound in air is 330 m/s. A note with a frequency of 1,320 Hz is played on an instrument. What is the wavelength of that sound wave?

Answer 1

0.25 m

Step-by-step explanation:

Just took the quiz on Edg

Answer 2

As we know that speed of sound is

`v = 330 m/s`

frequency of sound is

`f= 1320 Hz`

now we know that frequency of sound and speed of sound is related to each other by the following formula

`speed = frequency * wavelength`

`v = \lambda * f`

`330 = 1320 * \lambda`

`\lambda = 0.25 m`

so wavelength of sound is 25 cm or 0.25 m
