Select True or False for the following statements about electromagnetic waves. The sun's radiation is most intense in the visible region. Radio waves travel in vacuum at a lower speed than the visible light. The Earth's atmosphere is quite transparent to infrared radiation. Gamma rays can be produced through electrons oscillating in wires of electric circuits. Visible light is often emitted when valence electrons change their state. A vertical automobile antenna is sensitive to electric fields polarized vertically. X-rays travel in vacuum at a higher speed than the visible light.

Almost everything we know about the universe comes from information carried in electromagnetic radiation: radio waves, microwaves, X-rays, visible light, and gamma waves have been travelling to us for billions of years, all at the speed of light. Using spectroscopes that work on the same principle as the ones we used in lab, scientists read the line spectra that the hot gases emit to determine the elements that compose the stars. Explain.
