A stellar object is emitting radiation at 1670 nm. If the detector is capturing 9 * 10^7 photons per second at this wavelength, what is the total energy of the photons detected in one hour?
1 Answer
Explanation:
The formula for finding the energy of a photon is;
Where
Planck's constant in terms of electron volts is
We are given the rate,
Now we can calculate the total energy received over an hour. There are
For comparison, this is about 1 billionth of the energy given off by a 100 watt light bulb each second.
