Which sequence of electromagnetic radiations is in order of increasing wavelength?

Explanation:
Wavelength increases as you move from higher-energy photons to lower-energy ones, so order from shortest to longest wavelength. X-ray light has the shortest wavelength among these, followed by visible light, then infrared, with radio waves having the longest wavelength. Therefore the correct sequence is X-ray, visible, infrared, radio. Any sequence that starts with radio, or that places infrared before a shorter-wavelength light, breaks the increasing-wavelength order.
