There is no angle of refraction]]> 2018-05-07 17:19:56 UTC https://padlet.com/lopezste007/3zha9f2gcdcl/wish/258633493 How to find the angle of refraction lopezste007 https://padlet.com/lopezste007/3zha9f2gcdcl/wish/258974546 find θ1 or the angle of incidence 

find n1 or the index of refraction of the first substance

Find n2 or the index of refraction of the second substance

use the following equation to find θ2 rearrange it if necessary:

n1sin(θ1)=n2sin(θ2)

θ2= sin^-1(n1sin(θ1)/n2)]]> 2018-05-08 16:00:30 UTC https://padlet.com/lopezste007/3zha9f2gcdcl/wish/258974546 How to find the index of refraction lopezste007 https://padlet.com/lopezste007/3zha9f2gcdcl/wish/258978711 Find θ1

then the speed of light decreases
(ex. light travelling from air to water n1=1 n2=1.33)

If light travels from a higher index of refraction to a lower index of refraction then the speed of light increases
(ex. light travelling from diamond to air n1=2.42 n2=1]]> 2018-05-08 17:15:48 UTC https://padlet.com/lopezste007/3zha9f2gcdcl/wish/259008394
