Apolarized light beam, with a 7.55 mm diameter circular cross section, is perpendicularly incident on an ideal polarizer, serving as an analyzer. the intensity of the light is 3.87 kw/m2 and the angle between the beam's polarization direction and the polarization axis of the polarizer is 19.9∘. what force in piconewtons does the light exert on the polarizer?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

What accounts for an increase in the temperature of a gas that is kept at constant volume? a. energy has been removed as heat from the gas. b. energy has been added as heat to the gas. c. energy has been removed as work done by the gas. d. energy has been added as work done by the gas.
