If a glass of water and a clear diamond have the same index of refraction....

• light will reflect and refract

• light will not change speed or refract

• light will not reflect or refract due to the materials in either substance

• speeds will be very different and the light will refract a lot.

In a physics demonstration, Leo uses a polarizer to analyze the properties of light. What happens to unpolarized light when it passes through a polarizer?

• It becomes polarized along the axis of the polarizer.

• It completely loses its intensity.

• Its wavelength doubles.

• It becomes unpolarized light with half the original intensity.
