A light ray in air ($$n = 1.00$$) is incident on an unknown material at an angle of $$60^\text{o}$$ with respect to the normal. The ray refracts into the material at an angle of $$35^\text{o}$$ with respect to the normal. Which of the following describes the change in the light’s wavelength?
A
Remains unchanged
B
Increases by a factor of 1.44
C
Decreases by a factor of 0.574
D
Decreases by a factor of 0.662
