Visible light is often emitted when valence electrons change their state.

True. Valence means outer electrons. When they change state, visible light is emitted

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

True

------------------------------------------------------------------------------------------------------------------------------
Blue light has a longer wavelength than red.

False. Red light has the maximum wavelength (VIBGYOR)

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

False

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

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...
