HELP!!!!!!!!!!!!

how can the answer not be in ur textbook?

 

[Phoenix Fury]

I don't have a textbook that explains it and our teacher is no where
ergo, im screwed as well.

Snell's law is the basic law of refraction. He found that for a given pair of materials:

Sin I/Sin R = Refractive Index where

I - Incident Ray
R - Refracted Ray

 

[Fortify]

Remember the formula:

n = sin i / sin r = v1 / v2 = λ1 / λ2 = n2 / n1

n = Refractive index
i = angle of incidence
r = angle of refraction
λ = wavelength
v = velocity


Here are some worksheets for last minute revision.

yeah snell's law is basically finding out the refractive index of the particular substance or the refractive index of the boundary of two substances

there are different ways for find the refractive index

sini/sin r= v1/v2 = n2/n1 (n refers to the refractive index)

Fortify, i think you got the n1/n2 wrong

 

[Fortify]

oh yeh soz my bad

 

[bored of sc]

the angle of incidence is the same as the angle of reflection

lol, year 10 science

don't know about all this refraction stuff but its sounds pretty complex

is it??
