   The light particle conceived by Einstein is called a photon. The main point of his light quantum theory is the idea that light's energy is related to its oscillation frequency (known as frequency in the case of radio waves). Oscillation frequency is equal to the speed of light divided by its wavelength.

   If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.

   Jul 16, 2020 · Light is a form of energy that travels as waves. Their length — or wavelength — determines many of light’s properties. For instance, wavelength accounts for light’s color and how it will interact with matter.

   What is a range of wavelengths called?

   • The range of wavelengths, from super short to very, very long, is known as the light spectrum. Whatever its wavelength, light will radiate out infinitely unless or until it is stopped. As such, light is known as radiation. Light’s formal name is electromagnetic radiation. All light shares three properties. It can travel through a vacuum.

   Is light a wave?

   • This difficulty gets greatly magnified for the case of light. 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.

   What consists of more than visible light?

   • The electromagnetic spectrum consists of much more than visible light. It includes wavelengths of energy that human eyes can’t perceive. What Is the Electromagnetic Spectrum? The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see.

   Which part of the spectrum does light fall in?

   • Long, low-energy waves of light fall in the radio and microwave part of the spectrum. Electromagnetic radiation includes waves that are bigger than the largest buildings and waves that are smaller than the tiniest particles known. Visible light makes up only a tiny slice of this range.
