Photo Challenge: Refraction

This week, let’s play with light! Show us what refraction means to you.


The ratio of the sines of the angle of incidence θ1 to the angle of refraction θ2 is equal to the ratio of phase velocities (v1 / v2) in the two disparate media. It is also equal to the opposite ratio of the indices of refraction (n2 / n1)
