Q1. The red giant Betelgeuse has the surface temperature of 4000 {rm K} and is 500 times the diameter of our sun. (If our sun were that large, we would be inside it!) Presume that it radiates like an ideal blackbody.

Q2. Find the transmitted intensity for each of these solutions when placed between crossed polarizers. The incident beam is unpolarized and has intensity of 11.0 {rm W/m^ {2}}.

Q3. Albert is piloting his spaceship, heading east with a speed of 0.88. Albert's ship sends a light beam in forward (eastward) direction, which travels away from his ship at a speed. Meanwhile, Isaac is piloting his ship in the westward direction, also at 0.89, toward Albert's ship. With what speed does Isaac see Albert's light beam pass his ship?
