Question

A transverse wave is observed to be moving along a lengthy rope. Adjacent crests are positioned 2.4 m apart. Exactly six crests are observed to move past a given point along the medium in 9.1 seconds. Determine the frequency of these waves

Answer 1

Answer:

f = 0.65 hz

Explanation:

Given that,

The distance between adjacent crests, wavelength = 2.4 m

6 crests are observed to move past a given point along the medium in 9.1 seconds.

We need to find the frequency of these waves.

We know that,

Frequency = no. of waves per second.

$f=\dfrac{6}{9.1}\ Hz\\\\=0.65\ Hz$

So, the frequency of these waves is equal to 0.65 Hz.
