Question

The correct order of arrangement of electromagnetic waves according to their wavelengths is

• A. \(Gamma rays<AM radio waves<FM radio waves<Micro waves\)
• B. \(Micro waves<AM radio waves<FM radio waves<Gamma rays\)
• C. \(Gamma rays<Micro waves<AM radio waves<FM radio waves\)
• D. \(Gamma rays<Micro waves<FM radio waves<AM radio waves\)
• E. \(AM radio waves<FM radio waves<Gamma rays<Micro waves\)

Hint:

Memorize the electromagnetic spectrum from gamma rays (shortest wavelength) to radio waves (longest wavelength) for easy reference.

Answer 1

The Correct Option is D

Step 1: Gamma rays have the shortest wavelengths in the electromagnetic spectrum. 
Step 2: Microwaves have longer wavelengths than gamma rays but shorter than radio waves. 
Step 3: Within radio waves, FM waves have shorter wavelengths compared to AM waves. 
Step 4: Thus, the correct order from shortest to longest wavelength is gamma rays, microwaves, FM radio waves, and AM radio waves.
