The Electromagnetic Spectrum

Question 1 • PARTA - EOP: PGCPS BIOGEOCHEM CR (FALL2026) - 798113

The energy of microwaves is less than the energy of ultraviolet light. Which comparison of the energies of electromagnetic waves is correct?

Answer
A
X-rays have lower energy than gamma rays because X-rays have higher frequencies.
B
X-rays have lower energy than gamma rays because X-rays have shorter wavelengths.
C
Visible light has higher energy than infrared light because visible light has longer wavelengths.
D
Visible light has higher energy than infrared light because visible light has higher frequencies.

Explanation

Energy increases with frequency and decreases with wavelength. Visible light has a higher frequency than infrared light, so visible light has higher energy. Choice D gives the correct comparison and reason; the other choices incorrectly relate energy to frequency or wavelength.
