Why?
From fireworks to stars, the color of light is useful in finding out what's in matter. The emission of g
by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms.
Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be
identified by heating or burning the materials and examining the color(s) of light given off in the form of
bright-line spectra.

17. An incident P-wave is converted into refracted and
reflected P- and S-waves at an interface that is
inclined at 20° to the horizontal, as in the figure
below. The respective P- and S-wave velocities are
5 km s-1 and 3 km s-1 above the interface and

Consider a road that runs parallel to the line connecting a pair of radio towers that transmit the same station (assume that their transmissions are synchronized), which has an AM frequency of 1000 kilohertz. If the road is 5 kilometers from the towers and the towers are separated by 400 meters, find the angle θ to the first point of minimum signal (m=0). Hint: A frequency of 1000 kilohertz corresponds to a wavelength of 300 meters for radio waves.
