Question

Select True or False for the following statements about electromagnetic waves.

True False  The Earth's atmosphere is quite transparent to infrared radiation.
True False  Gamma rays travel in vacuum at the same speed as the visible light.
True False  X-rays can be produced in transitions involving inner electrons in an atom.
True False  A vertical automobile antenna is sensitive to electric fields polarized horizontally.
True False  Blue light has a longer wavelength than red.
True False  Visible light is often emitted when valence electrons change their state.
True False  The sun's radiation is most intense in the infrared region.

Explanation / Answer

False....Most Infrared radiation is blocked by our lower atmosphere by water vapour

True..Gamma rays electromagnetic radiation which travel with light velocity

true

true

false... In the visible region blue comes first which is having less wavelength value compared to red

true....when outer most electrons (valency electrons) changes their states, transitions takes place visible light is produced

false ....since we can see the sun most intense radiation in the visible region
