Problem 4: Radiation from the Sun The intensity of the radiation from the Sun is 1360 W/m2 and frequency is f60 MHz. The distance between the Earth and the Sun is 1.5 x 1011m a) Assuming it radiates uniformly in all directions what is the total power output of the Sun? b) If the frequency increases by 1 MHz what would be the relative change in the power output?

At our distance from the Sun, the intensity of solar radiation is 1370 W/m2 . As discussed in class and in the textbook, the temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared radiation by the surface so as to make the surface temperature of the Earth higher than if it were airless. The average global surface temperature of the Earth is ~288 K. Calculate the surface...
