LO 8
Across
2. have wave fronts that lie in planes parallel to each other
3. shown by waves that are in phase
4. interference between waves travelling different paths when wavelengths are
comparable to objects' dimensions
7. the idea that all points on a wave front of light are sources of secondary waves and that
surfaces tangential to these waves define the position of the wave front at any point in
time
9. light that has a single wavelength
Down
1. shown by waves that are out of phase
5. a sound wave that can propagate in 3 dimensions
6. produce light that is monochromatic and coherent
8. increasing and decreasing amplitude that we hear when 2 waves have slightly different
frequencies
10. light that has the same phase
