Which of the following has the shortest wavelength?
A. X-rays
B. Infrared
C. Gamma rays
D. Ultraviolet
Answer: Option C
Solution (By JKExamLibrary)
Gamma rays have wavelengths < 10⁻¹² m, shortest in EM spectrum. X-rays 10⁻¹⁰-10⁻⁸ m. UV 10⁻⁸-4×10⁻⁷ m. IR longer. So gamma rays shortest. Highest frequency, energy.
