Homework Answers

Answer #1

True Gamma rays travel in vacuum at the same speed as the visible light.

as all the electro magnetic waves travel in the vaccum with same speed and gamma rays are also electro magnetic wave.

True Radio waves have wavelengths longer than 1 m.

as the wavelength of Radio waves is greater than the 1 mm to 100 km

False The sun's radiation is most intense in the visible region.

sun radiation is NOT most intense in the visible region.

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

False Radio waves have higher frequencies than gamma rays.

gamma waves have must higher frequency than gamma rays

False  Ultraviolet radiation causes common sunburn.

comman sunburn is caused by infrared.

True X-rays can be produced in transitions involving inner electrons in an atom.

for higher mass atoms , X rays can be produced in transitions involving inner electrons in an atom.
