Water waves are transverse waves - Edexcel - GCSE Physics - Question 3 - 2016 - Paper 1

An example of a longitudinal wave is a sound wave.

To calculate the speed of the wave, we use the formula:

$wave speed = \frac{distance}{time}$

Given that the distance traveled is 26400 m and the time taken is 2 minutes (which is equivalent to 120 seconds), we can substitute the values into the equation:

$wave speed = \frac{26400 \text{ m}}{120 \text{ s}}$

Calculating this gives:

$wave speed = 220 \text{ m/s}$

Thus, the speed of the wave is 220 m/s.
