# Distance between two points of differing phase

1. Jan 30, 2009

1. A wave has a wavelength of 20 cm. Calculate the minimum distance between 2 points on the wave which differ in phase by 60 degrees

2. ummmm

3. I have drawn a sine wave from 0 to 360, and have marked the point where 60 degress should be. I dont really know why though. Very stuck, even though it seems like an easy short question. Missing something here for sure.

Is it 3.33?

I need to learn the simple definition of what phase is I think.

EDIT: Doesn't matter, I've had to hand it in now. Just guessed at 3.33. Which is probably wrong, but it was only two marks so its not the end of the world.
