Question

Electromagnetic Spectrum can be broadly divided (in order of increasing wavelength)

• A. \( \text{X-rays, Gamma rays, Infrared, Ultraviolet, Visible, Radiowave, Microwave} \)
• B. \( \text{Gamma rays, X-rays, Radiowave, Microwave, Ultraviolet, Infrared, Visible} \)
• C. \( \text{X-rays, Gamma rays, Microwave, Radiowave, Ultraviolet, Infrared, Visible} \)
• D. \( \text{Gamma rays, X-rays, Ultraviolet, Visible, Infrared, Microwave, Radiowave} \)

Hint:

Remember the mnemonic "Rabbits Mate In Very Unusual X-tra Gardens" (Radio, Micro, Infra-Red, Visible, Ultra-Violet, X-ray, Gamma) for increasing frequency (decreasing wavelength), and reverse it for increasing wavelength.

Answer 1

The Correct Option is D

The electromagnetic spectrum, in order of increasing wavelength, is: Gamma rays, X-rays, Ultraviolet, Visible, Infrared, Microwave, Radiowave. Gamma rays have the shortest wavelengths and highest energy, while radio waves have the longest wavelengths and lowest energy.
