Which of the following represents the correct decreasing order of wavelengths for the given electromagnetic waves?
Options
- AMicrowaves > Red light > Blue light > X-rays
- BX-rays > Blue light > Red light > Microwaves
- CMicrowaves > Blue light > Red light > X-rays
- DRed light > Microwaves > X-rays > Blue light
Correct answer
A. Microwaves > Red light > Blue light > X-rays
Step-by-step solution
The complete electromagnetic spectrum in decreasing order of wavelength is: Radio waves > Microwaves > Infrared > Visible light > Ultraviolet > X-rays > Gamma rays.
Within the visible spectrum, wavelength decreases from red to violet (VIBGYOR). Therefore, red light has a longer wavelength than blue light.
Combining both sequences, the correct decreasing order of wavelengths is: Microwaves > Red light > Blue light > X-rays.
Answer: Microwaves > Red light > Blue light > X-rays
Within the visible spectrum, wavelength decreases from red to violet (VIBGYOR). Therefore, red light has a longer wavelength than blue light.
