- Light is called electromagnetic radiation, which basically means that it radiates (travels) and the wave part is oscillating electric and magnetic fields.

We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes this energy is obvious, such as in the warmth of the summer Sun. Other times, it is subtle, such as the unfelt energy of gamma rays, which can destroy living cells.
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they...
Jul 27, 2023 · Relate the wavelength and frequency of light using a mathematical equation. Define electromagnetic radiation. Light is a little different from sound waves, water waves and string waves, because it can move through a vacuum. In general, the velocity of light is constant, c = 3.00 x 10 8 m/s.
Light is a form of electromagnetic radiation (EMR). The term light usually refers to visible light, but this is not the only form of EMR. As we will see, visible light occupies a narrow band in a broad range of types of electromagnetic radiation.

The kinetic energy of the ejected electron is independent of the frequency of the light. Einstein (in 1905) proposed an explanation of the photoelectric effect that used the idea of quantization. The quantization model assumes that the energy of a light wave is present in particles called photons.
