Question

2.

A dolphin can hear sounds with frequencies up to 280 kHz. What is the
speed of sound in water if a wave with this frequency has a wwavelength
of 0.51 cm?

Answer 1

1428 m/s

Step-by-step explanation:

Given that,

The frequency hear by a dolphin, f = 280 kHz

We need to find the speed of sound in water if a wave with this frequency has a wavelength of 0.51 cm.

The formula for the speed in terms of wavelength and frequency is given by :

`v=f\lambda\\\\v=280* 10^3* 0.51* 10^(-2)\\\\v=1428\ m/s`

So, the speed of sound in water is 1428 m/s.
