Question

What is the wavelength of an earthquake wave if it has a speed of 10 km/s 3 points

and a frequency of 15 Hz?*
.67 km
1.5 km
150 k

Answer 1

0.67 km

Step-by-step explanation:

Given that,

The speed of a wave, v = 10 km/s = 10000 m/s

The frequency of a wave, f = 15 Hz

We need to find the wavelength of the wave. The speed of wave in terms of wavelength and frequency is given by :

`v=f\lambda\\\\\lambda=(v)/(f)\\\\\lambda=(10000)/(15)\\\\=666.66\ m`

or

= 0.67 km

So, the wavelength of the wave is 0.67 km.
