What can you infer from the image? (assume the purple arrow is a light beam)
The index of refraction for medium 2 must be higher than the index of refraction for medium 1.
The index of refraction for medium 1 must be higher than the index of refraction for medium 2.
The index of refraction for medium 1 must be approximately the same as the index of refraction for medium 2.

Imagine a light beam traveling from medium 1 into (and through) medium 2, just like in the simulation. The angle of incidence is 44 deg, and the index of refraction of medium 1 is 2.4. The light bends away from the normal a little bit, and the angle of refraction, when measured, turns out to be 56 deg. Calculate the index of refraction of medium 2 (remember, "medium" is a material that light moves through). Type your answer as a decimal number
