Question

A small hummingbird flying around beats its wings with a frequency of 170 Hz. If the wavelength of the sound wave produced is 2 m, what is the speed of the sound wave?

Answer 1

The given information in the question is :

Frequency = 170 Hz

1 Hz =
`(1)/(s)`

Frequency = 170
`(1)/(s)`

Wavelength given = 2 m

Speed is unknown which we need to calculate.

Speed can be calculated by using the formula : Speed = wavelength X frequency

By plugging the value of wavelength and frequency in the above formula we get :

Speed =
`(2m)* (170(1)/(s))`

Speed = 340
`(m)/(s)`
