Visible light is often emitted when valence electrons change their state.
Blue light has a higher frequency than X-rays.
The sun's radiation is most intense in the infrared region.
The Earth's atmosphere is quite transparent to infrared radiation.
X-rays are produced by a glowing light bulb.
A vertical automobile antenna is sensitive to electric fields polarized vertically.
Gamma rays can be produced through electrons oscillating in wires of electric circuits.
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)
