Arrange the following bands of the electromagnetic spectrum in ascending order of their wavelength:

A. X-rays
B. Near Infrared rays
C. Microwaves
D. Visible Rays
E. Radio waves

Choose the correct answer from the options given below:

Correct option is D

The ascending order of wavelength in the electromagnetic spectrum follows the pattern:

1. X-rays (A) → Shortest wavelength, highest energy
2. Visible Rays (D) → Shorter than infrared but longer than X-rays
3. Near Infrared Rays (B) → Longer than visible light
4. Microwaves (C) → Longer than infrared rays
5. Radio Waves (E) → Longest wavelength, lowest energy

Thus, the correct sequence is: A (X-rays) → D (Visible Rays) → B (Near Infrared Rays) → C (Microwaves) → E (Radio Waves)

• X-rays (A) have wavelengths between 0.01 nm and 10 nm, used in medical imaging and crystallography.
• Visible Rays (D) range from 400-700 nm, forming the spectrum of colors.
• Near Infrared Rays (B) range from 700 nm to 1 mm, used in remote sensing and night vision.
• Microwaves (C) range from 1 mm to 1 m, used in communication and radar systems.
• Radio Waves (E) have wavelengths above 1 meter, used for radio, TV broadcasting, and astronomy.
