Question

Waves are observed to splash upon the rocks at the shore every 6.0

Answer 1

Explanation:

Given that,

Waves are observed to splash upon the rocks at the shore every 6.0  seconds

The distance measured from crest to adjacent crest is 8.0  m

The distance measured from the lowest to the highest point on  the medium is 10.0 m.

We need to find the frequency, wavelength and  speed of these waves. We know that the distance measured from crest to adjacent crest is called wavelength of a wave. So, $\lambda=8\ m$

The inverse of time taken by the wave is called its frequency,

$f=\dfrac{1}{T}$

$f=\dfrac{1}{6\ s}$

f = 0.167 Hz

The speed of a wave is the product of frequency and wavelength. It is given by :

$v=f\times \lambda$

$v=0.167 \times 8$

v = 1.336 m/s

Hence, this is the required solution.
