   What are the properties of light in physics?

   • In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization.

   What is light energy?

   • Light energy is one of those. Lives on the Earth are highly dependent on the energy of light in many aspects. Sun is the only natural source of light in Earth. We are using sunlight directly and indirectly in our daily life. In this conceptual discussion, I’m going to explain the definition, sources, properties, examples and uses of light energy.

   • Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.

   Why is light energy called light energy?

   • This energy is called light energy or simply, the light. Sun is the source of light and all other energies. Because all other forms of energy are the transformed forms of the light energy coming from the Sun. A hot body emits energy in the form of light. If we heat a body, it will glow at high temperature and will emit lights.
