Question

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

• A. X-rays, Gamma rays, Infrared, Ultraviolet, Visible, Radiowave, Microwave
• B. Gamma rays, X-rays, Radiowave, Microwave, Ultraviolet, Infrared, Visible
• C. X-rays, Gamma rays, Microwave, Radiowave, Ultraviolet, Infrared, Visible
• D. Gamma rays, X-rays, Ultraviolet, Visible, Infrared, Microwave, Radiowave

Hint:

The electromagnetic spectrum is ordered based on wavelength, from the shortest (Gamma rays) to the longest (Radiowaves).

Answer 1

The Correct Option is D

The electromagnetic spectrum is divided based on the wavelength of different types of electromagnetic radiation. The order from shortest to longest wavelength is as follows:
- Gamma rays have the shortest wavelengths.
- X-rays follow next.
- Ultraviolet light comes after X-rays.
- Visible light has a longer wavelength than ultraviolet.
- Infrared radiation has a longer wavelength than visible light.
- Microwaves follow infrared.
- Radiowaves have the longest wavelengths.
Step 1: Correct Order of Electromagnetic Waves
By considering the wavelength of each type of radiation, we can order them as:
\[ \text{Gamma rays}<\text{X-rays}<\text{Ultraviolet}<\text{Visible}<\text{Infrared}<\text{Microwave}<\text{Radiowave}. \] Step 2: Conclusion
The correct sequence is (D) Gamma rays, X-rays, Ultraviolet, Visible, Infrared, Microwave, Radiowave.
