Let us suppose the initial velocity (u) and the final velocity (v) of a car. So here v = 0 the vehicle stops.

By 3^rd law of equation of motion,

v² - u² = 2aS₁

0 - u² = 2aS₁

The correct answer is Radio > Microwave > Infrared > Visible.

Key Points

• The electromagnetic (EM) spectrum describes all the wavelengths of light.
• From highest to lowest frequency (or from shortest to longest wavelength), the order of the EM spectrum is
  • Gmma rays, X-rays, Ultraviolet (UV) light, Visible Light, Infrared (IR) Light, Microwaves, and Radio waves.
• Radio waves:
  • ​These have the longest wavelengths in the electromagnetic spectrum, typically longer than 1 millimeter.
  • They are used for communication such as in radio and television broadcasting, cell phones and satellite communications.
• Microwaves:
  • ​Microwaves have shorter wavelengths than radio waves, typically in the range of 1 millimeter to 30 centimeters.
  • Microwaves are used for radar, satellite communication, and also for cooking in microwave ovens.
• Infrared waves:
  • ​Infrared waves, or infrared light, has wavelengths shorter than microwaves, generally in the range from 700 nanometers (nm) to 1 millimeter (mm).
  • Our skin emits infrared light, which is why it can be seen in the dark by night-vision goggles.
  • Infrared waves are also used for thermal imaging, remote controls, and in some forms of communication.
• Visible light:
  • ​This is the portion of the EM spectrum that human eyes can perceive.
  • It ranges from about 400 nm to about 700 nm in wavelength.
  • This light is emitted by the sun, light bulbs, etc. and is detected by the human eye.
• Ultraviolet light (UV):
  • ​UV light has shorter wavelengths than visible light, typically in the range of 10 nm to 400 nm.
  • It is used in tanning beds, can be emitted by the sun and black lights, and is the type of light that causes materials to fluoresce.
• X-rays:
  • ​X-rays have wavelengths shorter than UV light, typically in the range of 0.01 nm to 10 nm.
  • X-rays are used for medical imaging and also in some industrial imaging processes.
• Gamma rays:
  • ​These have the shortest wavelengths of the EM spectrum, typically smaller than 0.01 nm.
  • They are used in radiation therapy for cancer and are produced naturally in many decay processes such as from certain types of radioactive isotopes.
• Therefore, the correct order of the options you provided from longest to shortest wavelength (lowest to highest frequency) is: Radio > Microwave > Infrared > Visible.
