How does the speed of visible light compare with the speed of gamma rays, when both speeds are measured in a vacuum? a. the speed of visible light is greater b. speed of gamma rays is greater c. speeds are the same d. no answer can be determined from the information given

C. Speeds are the same

Explanation:

Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them.

Electromagnetic spectrum involves gamma rays , X rays, ultra violet rays, visible rays, infrared rays, micro waves and radio waves which are arranged in order of increasing wavelength and decreasing frequency.

They all travel with the speed of light.The energy transport through a medium involves the absorption and re emission of the wave energy by the atoms of the material.
