Reading quiz Which of the following is NOT true of the wave vector? a. a.Its magnitude is equal to 2  /. b. b.In a plane wave it points in the same direction everywhere in space. c. c.In a spherical wave it points in the same direction everywhere in space. d. d.It tells us which way the wave is going. e. e.In one dimension it reduces to the wave number k.

Waves in 3-dimensions Plane waves a. a.polarization Wave vector a. a.direction of wave Spherical waves

Student-designed problem What direction do you want the wave to be traveling in? What direction do you want the wave to be oscillating in? What wavelength do you want the wave to have? What do you want the wave’s amplitude to be? What frequency (or velocity) do you want the wave to have? What do you want the overall phase of the wave to be?

Lasers What makes a laser special? (answers from class) Some of my answers: a. a.Single wavelength b. b.Intense c. c.Collimated d. d.Coherence (spatial, temporal) % Actual laser spectrum over 100  narrower than the width of the red line Blackbody spectrum Laser spectrum
