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?

Respuesta :

Answer:

1428  m/s

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 :

[tex]v=f\lambda\\\\v=280\times 10^3\times 0.51\times 10^{-2}\\\\v=1428\ m/s[/tex]

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