1. LASER
Light Amplification by the Stimulated Emission of
Radiation
Monochromatic (one color) coherent (same frequency, in
phase) light

2. Interference and diffraction
Light falling on two slits will produce an
interference pattern
(Young’s two-slit experiment)

3. Interference and diffraction
Light falling on two slits will produce an
interference pattern
(Young’s two-slit experiment)

5. x
/ L = /dλ
x = how far apart (bright spots) are
L = distance from slits to screen
d = distance between slits, wires on a mesh,
tracking grooves on a CD, thickness of a
human hair
Using a set distance from the wall (L),
measure the distance between dots (x) and
calculate d
