A light goes from a material with a lower index of refraction $n_{1}$ into a material with a higher index of refraction $\mathrm{n}_{2}$ with an angle of incidence of $30.0^{\circ}$, which of the following is true?
A) the angle of refraction is less than $30.0^{\circ}$ and total internal reflection is not possible
B) the angle of refraction is less than $30.0^{\circ}$ and total internal reflection may occur
C) the angle of refraction is more than $30.0^{\circ}$ and total internal reflection may occur
D) the angle of refraction is more than $30.0^{\circ}$ and total internal reflection is not possible

When light moves from a material with a lower index of refraction to a material with a higher index of refraction, the angle of refraction is less than the angle of incidence, and total internal reflection cannot occur because it requires light to move from a higher to a lower index of refraction.
