Electromagnetic Waves: Ordering by Wavelength
The arrangement of electromagnetic waves is determined by their wavelength ($\lambda$), frequency ($f$), and energy ($E$). These properties are related: as wavelength increases, frequency and energy decrease. The order from shortest wavelength (highest frequency/energy) to longest wavelength (lowest frequency/energy) is key.
Standard EM Spectrum Order (Increasing Wavelength)
The main types of electromagnetic waves, ordered by increasing wavelength, are:
- Gamma rays (A)
- Ultraviolet rays (D)
- Visible rays (C)
- Infrared rays (B)
- Radio waves (E)
This order corresponds to decreasing frequency and energy.
Sequence Analysis
Matching the given waves to their position in the spectrum by wavelength:
A. Gamma rays: Shortest wavelength
D. Ultraviolet rays: Shorter than visible
C. Visible rays: Middle range
B. Infrared rays: Longer than visible
E. Radio waves: Longest wavelength
Therefore, the correct arrangement in increasing order of wavelength is A, D, C, B, E.
