Malak:
Sorry My internet is really slow  >:(, i am typing the answer for 21 c and the scan is still loading, Please bear with it

The Golden Girl =D:
It's Okay :D

Romeesa-Chan:
How do we find volume of air in a measuring cylinder?

Malak:
21 c attached (I find it easier typing in word 'cause the formulas are clear)

And for 19, yes its correct
By the way, for part a (the blue ray) it doesnt reflect 'cause its the cricital angle so it should pass along the prism ( 90 degrees)

Edit: the answer for R is 1.76 * 10^-3, just to confirm for you
And lol, thanks to your scan I realized that the angle is 'c', because I had refracted the blue light  ::)
