Nature of light
5
• Wave-particle duality Photons
• E=hν=h / p
• Light behaves like waves in its propagation and in phenomena of interference and diffraction;
• However, it exhibits particle-like behavior when exchanging energy with matter, as in the Compton and photoelectric effects
6
• E = mc2 + Ek
• rest-mass kinetic
• energy energy
• Photon m=0 zero rest mass
7
• Electrons obey Fermi-Dirac Statistics
no two e- in the same state, same physical
properties
• Photons obey Bose-Einstein statistics
identical photons with the same energy, momentum, and polarization can occur together in large numbers

Consider a Φe ＝ 5mW He － Ne laser emitting a beam with a divergence angle αof 1.3mradians. The laser cavity is designed so that the beam emerges from a surface area ∆As=2.5x10-3 cm2 at the output mirror.
a. Determine the solid angle ∆ in term of R and α.b. Determine the radiance of this laser light source in units of
