It is asking you to identify the material from the index of refraction.
n=3E8/1.94E8= 1.55
I bet your teacher gave you a table of materials from which you can id the material. Looks like flint glass to me.

A ray of light with wavelength 589 nm passes through an unknown material with a velocity of 1.94 x 10^8 m/s. What is the material?
I think this problem has something to do with Snell's law, but there is no given angle of refraction so I don't know how to solve it. Thanks!
