The electromagnetic spectrum encompasses a vast range of wave types, each characterized by its unique wavelength and frequency. Understanding the relationship between these two properties is key to answering the question: which wave has the shortest wavelength?

Wavelength and Frequency: An Inverse Relationship

Before we identify the wave with the shortest wavelength, it's important to establish the fundamental relationship between wavelength and frequency. These two properties are inversely proportional. This means that as the frequency of a wave increases, its wavelength decreases, and vice-versa. The speed of the wave remains constant. For electromagnetic waves, this constant speed is the speed of light.

The Electromagnetic Spectrum: A Hierarchy of Waves

The electromagnetic spectrum arranges electromagnetic waves in order of increasing frequency (and decreasing wavelength). This spectrum includes, from longest wavelength to shortest:

• Radio waves: These have the longest wavelengths and lowest frequencies. They are used extensively in communication technologies.
• Microwaves: Shorter wavelengths than radio waves, microwaves are used in ovens and radar systems.
• Infrared radiation: Felt as heat, infrared radiation is emitted by all objects.
• Visible light: The only part of the electromagnetic spectrum visible to the human eye. It comprises the colors of the rainbow, from red (longest wavelength) to violet (shortest wavelength within visible light).
• Ultraviolet (UV) radiation: Invisible to the human eye, UV radiation causes sunburns and can damage DNA.
• X-rays: High-energy waves used in medical imaging.
• Gamma rays: The waves with the shortest wavelengths and highest frequencies, gamma rays are highly energetic and potentially dangerous.

The Answer: Gamma Rays

Therefore, the wave with the shortest wavelength is the gamma ray. These waves possess incredibly high frequencies and correspondingly short wavelengths, making them the most energetic form of electromagnetic radiation. Their high energy is a consequence of their short wavelength, which dictates their strong interaction with matter.
