Homework Statement
Calculate the angle of incidence for an angle of refraction of 10° for
a) Diamond (2.42) to air
θ2=Angle of refraction=10°
n2=Index of refraction on refractive medium=1
n1=index of refraction on incident medium=2.42
θ1=?
Homework Equations
n1sinθ1=n2sinθ2
The Attempt at a Solution
The book's answer tells me the answer is 24.8°
I rearranged the equation to find theta1 or the angle of incidence
θ1=sin inverse(n2sinθ2/n1)
I substituted the values and I got 4.1°
Can someone help me? I can't figure out what I did wrong. Light is coming from a dense medium to a less dense medium (diamond to air) so where the incident ray originated from the dense medium which is n2. So confused..
