How to find photons per second?
Understand the Problem
The question is asking how to calculate the number of photons emitted or passing through a specific area in one second. This typically involves concepts from physics, specifically related to light and energy.
Answer
N = P / E, where E = hc/λ or E = hν.
The final answer is the number of photons emitted per second: N = P / E, where E = hc/λ or E = hν.
Answer for screen readers
The final answer is the number of photons emitted per second: N = P / E, where E = hc/λ or E = hν.
More Information
The energy of a photon is tied to its wavelength or frequency, which means different colored lights or electromagnetic waves emit different numbers of photons for the same power.
Tips
Common mistakes include not converting units correctly, especially wavelength to meters, and not using the correct value for physical constants like Planck's constant.
