Question

It is a packet of electromagnetic energy

A. Gamma Ray
B. Radiowaves
C. Infrared
D. Ultraviolet Rays​

Answer 1

Answer:

a.Gamma-rays

Gamma-rayshave the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.

These waves are generated by radioactive atoms and in nuclear explosions.

b.Radio waves

b.Radio waveshave the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones.

c.Infrared

Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum.

d.Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet. The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy.
