Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. This includes:
Ultraviolet
Ultraviolet light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays.
Radiation therapy
Radiation therapy or radiotherapy is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator.
Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
X-ray
Medical imagingAn X-ray is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
Electromagnetic radiation
Field of studyIn physics, electromagnetic radiation consists of waves of the electromagnetic field, which propagate through space and carry momentum and electromagnetic radiant energy.
