The period of wave is the ?

[Tilly2]

What sort of wave?

[york310]

Time it takes for one complete oscillation

[bibblebub]

the inverse of the frequency

[Buenchico]

I was going to write 'the time taken to complete one full cycle' but 'one complete oscillation' is just as good.

It's represented by 'T' here:

[Buenchico]

"the inverse of the frequency" is equally correct!

[Buenchico]

Well, now that we've seen the actual question (and remembering that the period of a wave is a time, not a distance), the answer is 'D'.

[Psybbo]

Sorry to butt in, but lovely to see you Chris

(With apologies to Sunshine1763)

Thank you, Psybbo. I've been working away from home (with 12-hour shifts, doing work designed for two people all on my own) so I've not been around much lately.

A particular wave has a wavelength of 30 metees and a period of five seconds. What is its speed
A.6 meters per second
B.12 meters per second
C.30 meters per second
D.70 meters per second

[Buenchico]

Use the formula Speed = Wavelength ÷ Period (which you need to LEARN!!!) to work it out for yourself!

4.0 Students ought to be able to work this one out for their self, or at least know where to look it up.
