1. When the distance from the source of radiation is doubled, the amount of radiation received will be: Doubled Tripled Reduced by half none of the above
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?
Cellphone Radiation
Cellphone Radiation Points:3 At a distance of 5 cm, the microwave radiation from a cellphone has an intensity of 57 W/m2. The maximum permissible radiation leaking out from a microwave oven at the same distance is 10 W/m2. Compare the average electric fields generated by the two devices how many times stronger is the electric field that is generated by the cellphone than the maximum permissible field leaking from a microwave oven?

Problem 4: Radiation from the Sun The intensity of the radiation from the Sun is 1360 W/m2 and frequency is f = 60MHz The distance between the Earth and the Sun is 1.5 x 10 เร็3.1. 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/m^2 . 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...
A space probe which is a distance of 1.9x1010 m from a star measures the total intensity of electromagnetic radiation from the star to be 4.0×103 W/m² For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Energy in a sinusoidal wave. Part AIf the star radiates uniformly in all directions, what is its total average power output?

At our distance from the Sun, the intensity of solar radiation is 1370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the ef- fect of absorption of infrared light emitted by the surface so as to make the surface temperature of the Earth higher than if it were airless. For comparison, consider a spherical object of radius r with no atmosphere at the same distance from the Sun as the...
