Do you know about Snell's law ?

anonymous · Answer

No :l

anonymous · Answer

OK. Snell's law is 
$$\frac{sin _\ i}{sin _\ r} = refractive\  index$$

i = angle of incidence
and 
r = angle of refraction

anonymous · Answer

Can you find sin r now ?

anonymous · Answer

No and no :/ 1 im still confused on how its done and 2 I dont have a calculator

anonymous · Answer

I had one yesterday and i tried working it out and i had gotten 10

anonymous · Answer

Using Snell's law sin r = sin i / refractive index
So, sin r = 0.15/1.5 = 1/10 = 0.1 is the answer

anonymous · Answer

Okay it makes a bit more sense and im sorry for not being anything prepared at all :/

anonymous · Answer

It's ok :)
