Solar cells generally have an antireflection coating. Explain how this increases their efficiency.
A radio antenna 326 m in diameter receives a radio signal from a very distant object at perpendicular incidence. The radio signal is a continuous sine wave with an amplitude of Emax = 0.82x10-5 V/m. Assume that the antenna absorbs all the radiation that falls on the disk and calculate the power in Watts received by the antenna.

- Oxygenated hemoglobin absorbs weakly in the red (hence its red color) and strongly in the near infrared, whereas deoxygenated hemoglobin has the opposite absorption. This fact is used in a “pulse oximeter” to measure oxygen saturation in arterial blood.
