Consider the following types of electromagnetic radiation:
(1) Microwave (2) Ultraviolet (3) Radio waves
(4) Infrared (5) X-ray (6) Visible
(b) Arrange them in order of increasing frequency.

Respuesta :

X-ray <  Ultraviolet < Visible <  Infrared <Microwave <Radio waves

Applications of Electromagnetic Waves

Here are a few uses for electromagnetic waves:

  • In a vacuum or with no medium at all, electromagnetic radiation can transfer energy.
  • In modern communications technologies, electromagnetic waves are crucial.
  • RADARS employ electromagnetic waves.
  • UV rays are used to identify fake currency. Under UV light, genuine currency does not become fluorescent.
  • Security cameras use infrared radiation for night vision.

Electromagnetic wave              Wavelength

(1) Microwave               =                   1 m to 1 mm =  to

(2) Ultraviolet                =                  10 nm to 400 nm

(3) Radio waves           =                  1 mm to 100 km =  to

(4) Infrared                  =                      700 nm to 1 mm

(5) X-ray                      =                     0.01 nm to 10 nm

(6) Visible                   =                        400 nm to 700 nm

In order of increasing wavelength:

X-ray <  Ultraviolet < Visible <  Infrared <Microwave <Radio waves
