WebIncandescent light bulbs radiate 40 to 100 watts. The Sun delivers 1,360 watts per square meter. An astronaut facing the Sun has a surface area of about 0.85 square meters, so he or she receives energy equivalent to 19 60-watt … WebIncandescent light bulbs radiate 40 to 100 watts.

How do you calculate the number of photons? + Example …
WebPower is energy per unit time, and so if we can find the energy per photon, we can determine the number of photons per second. This will best be done in joules, since power is given in watts, which are joules per second. Solution The power in visible light production is 10.0% of 100 W, or 10.0 J/s. WebThe sun has a power output of 3.83 × 1026 W. Part A How many photons does the Sun emit each second? Assume that the average value of the wavelength of light emitted by the sun is 500 nm. Part B Installed on your roof is a solar panel that has a surface area of 1.90 m2 . How many photons from the Sun reach the panel? photo editing and restoration
Solar luminosity - Wikipedia
WebThis means, the energy emitted in one second = 25 × 10^ {-3} 25×10−3 J Number of photons in one second = \dfrac {25×10^ {-3}} {3.74×10^ {-19}} = 6.68 × 10^ {16} 3.74×10−1925×10−3 = 6.68×1016 Need a fast expert's response?

Luminosity is recorded in Joules per second internationally. The sun's … WebWe know that the Sun loses 3.78 x 10 26 Joules of energy every second (this is the Sun's luminosity). By using E = mc 2, figure out how much mass this corresponds to. That is, how much mass does the Sun lose every second? Express your answer in metric tons. (A metric ton = 1000 kg.)
