Light energy is of various types. They are: Visible light– Can only be seen through the naked eye. It’s a form of electromagnetic energy. The source of visible light is the sun. It can also emit from lanterns, flashlights, light bulbs, etc. Infrared light– is also a form of electromagnetic energy that produces heat. TV remotes use infrared light. T...
Intensity: Intensity of light is the rate at which the source releases the light energy. Its power unit is a watt. It is also describable as brightness measured at the rate at which light generates in a surface unit or energy per unit time per unit area. Frequency: Frequency of light is known as the number of crests that passes through a particular...
Light energy is measurable in various forms of units. 1. Angstrom and nanometers are useful to calculate the wavelength of the light. 2. Hertz units calculate the frequency of light energy. And, 3. Electron volts (eV) is the unit to calculate Light energy.

Higher energy light such as gamma rays, X-rays, and high energy UV light cause ionizations. They transfer enough energy to electrons so they can escape from the pull of the atom’s nucleus and turn the atom into an ion. Low energy UV and visible light cause electron transitions.
