You're right - I forgot about that.
They only produce constructive interference then. Looks like I'm forgetting some of my AS stuff already.
The earth takes one year to orbit the sun at a distance of 1.5*10^11m. Calculate it's speed. Explain why this is it's average speed and not it's velocity.
Can someone explain this plzzzzzzzz

maybe cuz it comes back to its original position after a complete round and displacement (in the case of velocity) becomes zero.
i think so

I think Silent Hunter is right cuz' I thought so 2.
During an orbit, the earth returns to its original position, which makes displacement 0. There no displacement ---> no velocity.
