Select True or False for the following statements about electromagnetic waves. Radio waves have wavelengths longer than 1 m. Radio waves have higher frequencies than gamma rays. The Earth's atmosphere is quite transparent to infrared radiation. The sun's radiation is most intense in the infrared region. Gamma rays travel in vacuum at the same speed as the visible light. X-rays travel in vacuum at a higher speed than the visible light. A vertical automobile antenna is sensitive to electric fields polarized horizontally.

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