Calculate the refractive index if the angle of incidence is 60° and the angle of refraction is 30°.
Use the formula μ = sin(i) / sin(r).
If the refractive index of a medium is 1.5 and the angle of incidence is 45°, what is the angle of refraction?
Rearrange the refractive index formula to find the angle of refraction.
What is the formula to calculate the refractive index?
Think about how you can express the relationship between these angles.
True or False: A higher refractive index results in light bending more.
Recall how refraction changes when light enters a denser medium.
Light travels from air (n=1) into a diamond (n=2.42); calculate the angle of refraction if the angle of incidence is 40°.
Rearrange Snell's Law to isolate sin(r) and calculate.
A ray of light enters a liquid from air at an angle of 50°, where the refractive index of the liquid is 1.5. Find the angle of refraction.
Apply the laws systematically and simplify before calculations!
