2a: The Earth is 1.5 x 10 from the Sun which radiates energy with an average power of 3.83 x 10 W...
Electromagnetic Wave Questions 2. Our sun has a power output of roughly 3.87 1026 watts (W). This energy is transmitted essentially uniformly in all directions. By the time this radiation reaches the Earth, which has an average distance from the sun of 1.50 x 10" m, what is the intensity? (Recall that intensity is defined to be power per unit area). 3. The energy from the sun is primarily in the infrared and visual wavelengths. The following table gives the...
I can see here that for question B Stefan–Boltzmann law was used. However, the energy per unit area is being divided per 4. why? The ratio distance of Mars from the Sun 1.5 6. distance of Earth from the Sun (a) Show that the intensity of solar radiation at the orbit of Mars is about 600 W m2 (b) Determine, in K, the mean surface temperature of Mars. Assume that Mars acts as a black body. 121 (c) The atmosphere...
Need help with question 6 and 7 t/T ZOOC S (W/m2) Lt/T 2.0 0.5 1.0 1.5 Target Area Interactive Exercises 33.03: Energy Transport and Electromagnetic Waves Consider sunlight that has been filtered so that only an electromagnetic wave of wavelength 1 = 500 nm is present. Because Earth is far from Sun, we will model this sunlight as a plane electromagnetic wave. The simulation (linked below) shows the traveling electric and magnetic waves. Run the animation now. A flat (planar)...
