The solar constant is the radiant flux density at a spherical surface centered on the Sun having a radius equal to that of the Earth's mean orbital radius; it has a value of $0.133-0.14 \mathrm{W} / \mathrm{cm}^{2}$. If we assume an average wavelength of about $700 \mathrm{nm}$, how many photons at most will arrive on each square meter per second of a solar cell panel just above the atmosphere?

The solar constant is the radiant flux density (irradiance) from the Sun at the surface of the Earth's atmosphere and is about 0.135 W/m². Assume an average wavelength of 700 nm for the sun's radiation that reaches the Earth. Find (a) the amplitude of the E-field and B-field, (b) the number of photons that arrive each second on each square meter of a solar panel, and (c) a harmonic wave equation for the E-field of the solar radiation, inserting all constants numerically.

Solar constant is defined as energy received by earth per $\mathrm{cm}^{2}$ per minute. The dimensions of solar constant are (b) $\left[\mathrm{M}^{2} \mathrm{~L}^{0} \mathrm{~T}^{-1}\right]$ (a) $\left[\mathrm{ML}^{2} \mathrm{~T}^{-3}\right]$ (c) $\left[\mathrm{ML}^{0} \mathrm{~T}^{-3}\right]$ (d) $\left[\mathrm{MLT}^{-2}\right]$
