Light travels at 3 x 10⁸ m/s in a vacuum what is the index of refraction of an oily solution if light travels at 1.5 x 10⁸ m/s? 

If light travels at c in a vacuum, 1.11 x 10⁸ m/s in silicone carbonide, and 2.3 x 10⁸ m/s in acetone. Which of the following correctly orders the different media from the lowest index of refraction to highest index of refraction?

If light travels at c in a vacuum, 1.11 x 10⁸ m/s in silicone carbonide, and 2.3 x 10⁸ m/s in acetone. Which answers correctly assigns the index of refraction values to each media?

Light travels through medium A at 1.2 x 10⁸ m/s then enters medium B which as an index of refraction of n=1.7. Light travels faster in:

Which of the following is closest to the wavelength of a photon that has a frequency of 6.3 x 10¹⁴ s^-1? (Note: c the speed of light = 3 x 10⁸ m/s)

If light has a frequency of 3.4 x 10¹⁴ s^-1 . What will the light’s wavelength be when it passes through a medium with an index of refraction of 2? (Note: when light enters a medium its frequency doesn’t change)
