we will take the plasticine and fix the wire to the ruler and then wrap it around the scale several times....then we will count the no. of turns and divide the reading/length by the no. of turns and take the average value.

hmm....
lets see then

dont they want the diameter of the wire? and not the reel???

its the same thing....see the length will be the diameter try to think...if u take a thread and wrap it around a scale and count the no. of turms u'll get the diameter...

how did u find that?

Thankyou
For b) it will be that=(length at one side-length on the other side)/no. turns=Ans(mm)
This gives us the average value

as in if there are 2 angles of refraction in a diagram which one to calculate

the one they ask for!!!

which diameter are they asking??

I guess ur confusing the emergent ray with the refracted

It would not fit the screen !! 15 hz need ten times more divisons on screen
