Select true or false for the following statements about electromagnetic waves. ultraviolet radiation causes common sunburn. visible light is often emitted when valence electrons change their state. the sun's radiation is most intense in the infrared region. x-rays can be produced in transitions involving inner electrons in an atom. a vertical automobile antenna is sensitive to electric fields polarized horizontally. blue light has a higher frequency than x-rays. gamma rays travel in vacuum at the same speed as the visible light.

Explanation:

ultraviolet radiation causes common sunburn  -- true

visible light is often emitted when valance electrons change their state .-true

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

X-rays can be produced in transition involving inner electrons in an atom -false

Electrons from the higher(outer) energy levels fill the vacancies in inner orbits

which create x rays

A vertical automobile antenna is sensitive to electric fields polarized horizontally.-true

Blue light has higher frequency than x rays -false

Gamma rays travel at the same speed as the visible light-true

Both are electromagnetic in nature.
