Explanation / Answer

Visible light is often emitted when valence electrons change their state - True

Blue light has a higher frequency than X-rays -----Flase

The sun's radiation is most intense in the infrared region------Flase ,

( The most intense area is the visible and UV spectrum.)

The Earth's atmosphere is quite transparent to infrared radiation--------False

X-rays are produced by a glowing light bulb.----------False

(X-rays can be produced in transitions involving inner electrons in an atom)

A vertical automobile antenna is sensitive to electric fields polarized vertically.---------True

Gamma rays can be produced through electrons oscillating in wires of electric circuits.----False

(Gamma rays can be produced in transitions of an atomic nucleus from one state to another)
