Concept:This question covers the organization of the electromagnetic spectrum by frequency and wavelength.
Solution:The correct order of the electromagnetic spectrum from lowest frequency (longest wavelength) to highest frequency (shortest wavelength) is:
$$\text{Radio waves} < \text{Microwaves} < \text{Infrared} < \text{Visible Light} < \text{Ultraviolet} < \text{X-rays} < \text{Gamma rays}$$
Thus, the sequence
Radio waves \( \rightarrow \) Infrared \( \rightarrow \) Ultraviolet \( \rightarrow \) Gamma rays is correctly arranged in order of increasing frequency.
Why other options are incorrect:- Other sequences place high-frequency waves (like gamma rays) before lower-frequency waves (like infrared or ultraviolet), violating the order of increasing frequency.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
