If the incident light is unpolarized, about how much of the light intensity gets through a plane polarizer? (give the answer as a decimal number.)

If you touch a hot light bulb and get burned, that is an example of a. radiation b. convection c. conduction

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?
