From our SI Prefixes we know that 1kHz = 1000 Hz

To find use the formula given in the question. If you get stuck post what you've tried

I have no clue where to start at all, I need some sort of explanation to this, my understanding of this is poor..

a. what is ms in the speed formula ?
b. how do I work out Hz ?
c. how do I work out the wavelength in metres ?

units of speed ... which is (meters per second)

b. how do I work out Hz ?

where is in m/s and is in m

c. how do I work out the wavelength in metres ?

from the given formula for

...

ok thankyou for that i'll give it a try
