A beam of light traveling in air enters a substance. If the angle of incidence is 35 ∘ and the angle of refraction is 25 ∘ , what is the index of refraction of the substance?
n1sin(theta)1=n2sin(theta)2 So would it be like 1.008*sin(35)=n2*sin(25) ????
Correct. Air has an index of refraction of approximately 1, and the angle of incidence is 35°. The substance has an unknown index of refraction n, and the angle of refraction is 25°.
