MR.BooMBastiC:
i wrote da same!!!!!!!!!

i knew others but i didnt knew how to use them!! :o :o :o :o

thukon:
I wrote micrometer screw gauge.
The refracted angle is 50 sumthing. All u ppl used the formula R.I.=sin i / sin r, but the thing you didnt realize was that the medium outside was air, so you actually have to substitute the r value.

yeah!!

well that is known as the {{principle of reversebility of light}}

MaNa:
i wrote a ruller too bcuz i similer question was there in paper 6
where they asked u the hight of the paper n then they ashked height of one
its i guess paper 6 06 :) so i remembered n i wrote it with correct methord :)
ii am not sure for the didode i wrote D :( n the i set the corrent form right to left :S
ad for the force thingi in newton i made a trianle not  parellogram :( iam soo depressed:'(

R.I = sin i/sin r ...
1.49 = sin 35 / sin r
and my answer was 23. something

it waz 25...not 35
