- An earth-orbiting satellite has solar energy–collecting panels with a total area of 4.0 m2 . If the sun’s radiation is perpendicular to the panels and is completely absorbed, find the average solar power absorbed and the average radiation-pressure forceWhat is the frequency in Hz of electromagnetic radiation with wavelength 1.5 km ?An old-fashioned incandescent bulb (100 W) has a tungsten filament inside which glows at a steady temperature of 24000C and radiates electromagnetic waves (part heat, part light). What is the surface area of the filament? Assume emissivity of tungsten is 0.35. a) 9.9*10-4 m2 b) 9.9*10-5 m2 c) 1.5*10-4 m2

If the average distance from Earth to theSun is 1.50 * 1011 m, at what rate does the Sun radiate energy?Problem: Radiation Related The energy flux associated with solar radiation incident on the outer surface of the earth's atmosphere has been accurately measured and is known to be 1,368 W/m^2. The diameters of the sun and earth are 1.39 X 10^9 and 1.27 x 10^7 m, respectively, and the distance between the sun and the earth is 1.5 × 10^11 m. (a) What is the emissive power of the sun? (b) Approximating the sun's surface as black, what is its temperature? (c) At what wavelength is the spectral emissive power of the sun a maximum? (d) Assuming the earth's surface to be black and the sun to be the only source of energy for the earth, estimate the earth's surface temperature.
- At a distance of 39 ft , an ionizing radiation source delivers 7.0 rem of radiation. How close can you get to the source without having any biological effects? The intensity of the radiation increases as you move closer to the radiation source according to the equation I1 / I2 =D22/D12Emergency responders for radioactive material incidents normally use the inverse square law of radiation to estimate the separation distance from the radioactive source. If a source has an intensity of 3.125 R/min at one foot from the source, solve for the distance in feet to the 5 mR/min boundary. Show your solution, including assumptions.Light with an average intensity of 1.7 x 106 W/m2 perpendicuarly hits a foil of mass 60 mg and an area 12 cm2. Assuming that the foil reflects the light completely, and that no other force is exerted on the foil, what is the speed of the foil after 15 seconds of exposure?

Assume the emissivity is 0.90, the temperature of the Earth is 15ºC , and that of outer space is 2.7 K. (b) Compare the intensity of this radiation with that coming to the Earth from the Sun during the day, which averages about 800 W/m2, only half of which is absorbed. (c) What is the maximum magnetic field strength in the outgoing radiation, assuming it is a continuous wave?In a dentist's office an X-ray of a tooth is taken using X-rays that have a frequency of 4.32 x 1018 Hz.
