Answer 2

Electromagnetic wave:

Explanation:

The electromagnetic wave of the 7800A to 10A wavelength range are as follows:

• Infrared rays
• Visible rays
• Ultraviolet rays

Infrared rays:

• IR spectrum is used in sensing and detection.
• Infrared radiation can helps local blood circulation and reduce muscle tension.
• Infrared can be used in communication.

• Visible light helps plants with photosynthesis.
• Visible light are used in lasers, LEDs, and fluorescent lamps which have the full range of visible light.

Ultraviolet rays:

• The ultraviolet rays are used to produce special lamps and very hot bodies (sun).
• UV lamps are used to destroy germs in water purifiers.
