Consider a parallel beam of light of wavelength 600nm and intensity 100W (`m^-2)`. (a) Find the energy and linear momentum of each photon. (b) How many photons cross 1 `cm^2` area perpendicular to the beam in one second?
Text Solution
AI Generated Solution
To solve the problem, we will break it down into two parts: (a) finding the energy and linear momentum of each photon, and (b) calculating how many photons cross a 1 cm² area perpendicular to the beam in one second.
### Part (a): Energy and Linear Momentum of Each Photon
1. **Calculate the Energy of Each Photon**:
The energy \( E \) of a photon can be calculated using the formula:
\[
E = \frac{hc}{\lambda}
