Given information

Given:- a. radio waves b. microwaves c. infrared radiation d. ultraviolet radiation 

Arrange all the above radiations in order of increasing wavelengths.

Step-by-step explanation

Step 1.

Electromagnetic radiations are waves with electric and magnetic fields oscillating mutually perpendicular to each other in space. All the electromagnetic waves are characterized by specific wavelengths, frequencies and energies.

Planck's equation gives the mathematical relation between the amount of energy per photon of the electromagnetic radiations and its wavelength.

Planck's equation:

 

Where,

   

 

 

 

From Planck's equation, it is evident that there exists an inverse relationship between energy per photon and the wavelength of light. As the wavelength increases, the energy per photon decreases.
