--- Quote from: idol2009 on June 02, 2009, 02:23:18 pm ---The refractive index is sin i/sin r if I am not mistaken, so why in the Oct/Nov 08 paper 3 mark scheme is the answer to question 6b) sin r /sin i? I can't seem to understand, even though the answer looks wrong...
If anyone could explain to me that would be really helpful!

see you always calculate sin i / sin r when a light ray passes from rarer medium to a denser medium. but at that instant, you should calculate using sin r / sin i because it's the other way round..... the ray inside the denser medium is going to pass out to the rarer medium. :D
and By the way, simply.me , i sent you m/j 08 marksheme.. :) :)
