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 Waves. Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation.
Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered.
May 24, 2024 · 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.
When we’re thinking of light as being made of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy. Meanwhile, when we think...

How does light behave?
In most situations, light behaves like a wave with properties like wavelength and frequency, and is subject to diffraction and interference. In some situations, light can be considered to behave like a particle called a photon. This particle has no mass, but carries a fixed amount of energy.
