West Ham United

West Ham United is a soccer team that Mr. Curtis the physics teacher likes.

Light refracts through surfaces such as a water drop according to Snell's law (n1 sin(theta1) = n2 sin(theta2)). n is the index of refraction (defined in the table for various materials). The graph in the large droplet shows some light reflecting off the drop and some refracting through it with changes in the angle theta.
