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...

The mean distance between the Earth and the Sun is 1.50×1011 m. The average intensity of solar radiation incident on the upper atmosphere of the Earth is 1390 W/m2. Assuming that the Sun emits radiation uniformly in all directions, determine the total power radiated by the Sun.

The amount of radiant power produced by the sun is approximately 3.9 × 1026 W. Assuming the sun to be a perfect blackbody sphere with a radius of 6.96 × 108 m, find its surface temperature (in kelvins).
Light and the Electromagnetic Spectrum Examples 1) The distance from the Sun to Earth is 1.50 x 1011 m. How long does it take for light to cover this distance? 2) Suppose a particular galaxy emits orange light with a frequency of 5.000 x 1024 Hz. If the galaxy is moving away from Earth with a speed of 3325 km/s, what is the frequency of the light when it is observed on Earth?
The sun has a power output of 3.83 × 1026 W. Installed on your roof is a solar panel that has a surface area of 1.40 m2 . How many photons from the Sun reach the panel? Assume that the average value of the wavelength of light is 580 nm. Assume also that the sun emits photons equally in all directions and that photons are not scattered or absorbed by atmosphere on their way to the panel. Use the average...
Earth has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Assume it is a uniform solid sphere. The distance of Earth from the sun is 1.50 x 1011 m. (Assume Earth completes a single rotation in 24.0 hours and orbits the Sun once every 365 Earth days.) (a) Calculate the angular momentum of Earth in its orbit around the Sun kg m2/s (b) Calculate the angular momentum of Earth on its axis kg...
During a solar eclipse the Moon is positioned directly between Earth and the Sun. Find the magnitude of the net gravitational force acting on the Moon then, due to both Earth and the Sun. The masses of the Sun, Earth, and the Moon are 1.99 x100 kg, 5.98 x1024 kg, and 7.36 x 1022 kg, respectively. The Moon's mean distance from Earth is 3.84 × 108 m, and Earth's mean distance from the Sun is 1.50 x 1011 m. The...
The intensity of radiation reaching the earth from the sun is 1350 W/m2. The earth's radius is 6.4 ´ 106 m. How big a force does this radiation exert on the earth? (Assume it is all absorbed.)
