Light from the sun arrives at the earth, an average of 1.50 x 10^11 m away, at the rate of 1.40 x 10^3 W/m^2, for an area perpendicular to the direction of the light. Approximate sunlight as monochromatic with a frequency of 4.57 x 10^14 Hz. How many photons fall per second on each square meter of the earth's surface directly facing the sun? What is the power output of the sun? How many photons per second does it emit? How many photons per cubic meter are there near the earth?

The energy flux of sunlight reaching the surface of the earth is $1.388 \times 10^{3} \mathrm{~W} / \mathrm{m}^{2} .$ How many photons (nearly) per square metre are incident on the Earth per second? Assume that the photons in the sunlight have an average wavelength of $550 \mathrm{~nm}$.
The average power generated by the Sun has the value $3.74 \times 10^{26} \mathrm{~W}$. Assuming the average wavelength of the Sun's radiation to be $500 \mathrm{~nm}$, find the number of photons emitted by the Sun in $1 \mathrm{~s}$.
