The electromagnetic waves: Visible, ultraviolet, infrared, gamma rays, X-rays in increasing order of their wavelengths is:
Show Hint
Wavelength increases as energy decreases across the electromagnetic spectrum.
Updated On: Jun 19, 2026
- Gamma rays, X-rays, ultraviolet, visible, infrared
- Infrared, visible, ultraviolet, X-rays, gamma rays
- Visible, infrared, ultraviolet, X-rays, gamma rays
- Visible, ultraviolet, infrared, X-rays, gamma rays
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Wavelength trend across the spectrum.
Wavelength increases from gamma rays to radio waves.
Step 2: Standard ascending sequence.
Gamma<X-rays<UV<visible<IR.
Step 3: Matching with options.
Only option (1) follows this increasing-wavelength order.
Step 4: Physical basis.
Gamma rays have the highest frequency and shortest wavelength; infrared lies at longer wavelengths.
Step 5: Conclusion.
The correct sequence is gamma rays, X-rays, ultraviolet, visible, infrared.
Wavelength increases from gamma rays to radio waves.
Step 2: Standard ascending sequence.
Gamma<X-rays<UV<visible<IR.
Step 3: Matching with options.
