Question

Select True or False for the following statements about electromagnetic waves. Visible light is often emitted when valence electrons change their state. A vertical automobile antenna is sensitive to electric fields polarized horizontally. X-rays travel in vacuum at a higher speed than the visible light. The sun's radiation is most intense in the visible region. Gamma rays can be produced through electrons oscillating in wires of electric circuits. Ultraviolet radiation causes common sunburn. Blue light has a higher frequency than X-rays.
