Gamma rays have the highest frequency and photon energy in the electromagnetic spectrum. They have extremely short wavelengths and are associated with nuclear processes and high-energy particle interactions. Read More: Gamma Rays
X-rays have frequencies and photon energies slightly lower than gamma rays. They are widely used in medical imaging, security screening, and industrial applications due to their ability to penetrate materials and reveal internal structures. Read More: X-rays
Ultraviolet rays have higher frequencies and photon energies than visible light. They are emitted by the Sun and play a crucial role in biological processes, such as vitamin D synthesis and triggering chemical reactions in the atmosphere. Read More: Ultraviolet Rays
Visible light is the portion of the electromagnetic spectrum visible to the human eye. Visible light is essential for vision. It has a range of frequencies and photon energies that allow us to perceive different colours. Read More: Visible Light
Infrared rays have lower frequencies and photon energies than visible light. They are associated with thermal radiation and are commonly used in night vision, remote sensing, and infrared spectroscopy applications. Read More: Infrared Rays
Radio waves have the lowest frequencies and photon energies in the electromagnetic spectrum. They are used for communication, broadcasting, and radar systems. Different portions of the radio wave spectrum are allocated for various applications, including AM and FM radio, television, and mobile communication. Read More: Radio Waves
Microwaves have slightly higher frequencies and photon energies than radio waves. They are commonly used in microwave ovens, satellite communication, and wireless technologies.
