  1. You were introduced to two very popular equations concerning electromagnetic energy: the speed of light and the energy emitted from photons. Using the equations below, you will solve basic electromagnetic problems:

    • Gamma-Rays
    • X-Rays
    • Ultraviolet (UV) Rays
    • Visible Light
    • Infrared (IR) Rays
    • Radio Waves
    • Microwaves

    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. Read More: Microwaves Understanding the electromagnetic spectrum allows us to explore the diverse range of electromagnetic radiation and its applications.

  2. Electromagnetic waves span a spectrum that ranges from long wavelength, low frequency radio waves to short wavelength, high frequency gamma rays.

  3. Heat radiation (as opposed to particle radiation) is the transfer of internal energy in the form of electromagnetic waves — typically infrared or visible light.

  4. Dec 8, 2023 · Electromagnetic radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays. Before 1873, electricity and magnetism were thought to be two different forces.

  5. The space between the Earth and the Sun is largely empty, without any possibility of heat transfer by convection or conduction. In these examples, heat is transferred by radiation. That is, the hot body emits electromagnetic waves that are absorbed by our skin: no medium is required for electromagnetic waves to propagate. Different names are ...
