Question

Consider a wave generator that produces 10 pulses per second. The speed of the waves is 300 cm/s. What is the wavelength of the waves?

Answer 1

I got `0.3m`

Explanation:

We have that the frequency should be: `f=10Hz` (number of complete pulses in one second);
having the speed `s` we can write:

`color(red)(s=flambda)`

where `lambda` is the wavelength.

We use your data (converting cm to m first getting `300/100m/s=3m/s`) and get:

`3=10lambda`

rearranging:

`lambda=3/10=0.3m`
