Verified step by step guidance
1
Identify the types of electromagnetic radiation given in the problem: infrared, green light, red light, radio waves, X-rays, and ultraviolet light.
Recall the order of the electromagnetic spectrum in terms of increasing wavelength: gamma rays, X-rays, ultraviolet light, visible light (violet to red), infrared, microwaves, and radio waves.
Within the visible light spectrum, remember that violet light has the shortest wavelength and red light has the longest. Therefore, green light has a shorter wavelength than red light.
Arrange the given types of electromagnetic radiation based on their position in the electromagnetic spectrum, starting from the shortest wavelength to the longest wavelength.
Verify the order by ensuring that each type of radiation correctly follows the sequence in the electromagnetic spectrum.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Electromagnetic Spectrum

The electromagnetic spectrum encompasses all types of electromagnetic radiation, arranged by wavelength. It ranges from gamma rays with very short wavelengths to radio waves with very long wavelengths. Understanding this spectrum is crucial for categorizing different types of radiation and their properties.

Electromagnetic Spectrum

Wavelength

Wavelength is the distance between successive peaks of a wave, typically measured in meters. In the context of electromagnetic radiation, different types of radiation are characterized by their wavelengths, which determine their energy and behavior. Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Frequency-Wavelength Relationship

Order of Radiation Types

Different types of electromagnetic radiation can be arranged in order of increasing wavelength. For example, X-rays have shorter wavelengths than ultraviolet light, which in turn is shorter than visible light (including green and red light), and radio waves have the longest wavelengths. This order is essential for understanding the properties and applications of each type of radiation.
