- 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
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understand electromagnetic spectrum.
Wavelength increases from gamma rays to radio waves.
Step 2: Standard order.
\[ \gamma < X\text{-rays} < UV < visible < IR \]
Step 3: Compare options.
Only option (1) matches increasing wavelength order.
Step 4: Physical reasoning.
Gamma rays have highest frequency and shortest wavelength. Infrared has longer wavelength.
Step 5: Final conclusion.
Thus correct sequence is gamma → X-rays → UV → visible → IR.
Step 6: Final answer.
\[ \boxed{\text{Gamma rays, X-rays, ultraviolet, visible, infrared}} \]
