Question

What is the wavelength of an earthquake wave if it has a speed of 15 km/s and a frequency of 15 Hz?

Answer 1

ANSWER

The wavelength of the earthquake wave is 1000 m

Step-by-step explanation

From the question;

the speed,

`c = 15 \: km {s}^( - 1) = 15000 \: m {s}^( - 1)`
frequency,

`f = 15 \: Hz`
The relationship between wavelength,frequency and speed of a wave is given as

`f = (c)/( \lambda)`
This implies that,

`{ \lambda} = (c)/(f)`

`{ \lambda} = (15000)/(15)`

`{ \lambda} = 1000 \: m`
Hence the wavelength of the earthquake wave is

`1000 \: m`
