Nosso canal de atendimento pelo WhatsApp. In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons.

Light in Physics is a type of energy that enables us to see with our eyes.

Final Thoughts

Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings. That is the reason we can see objects during daytime with the sunlight, or with a light bulb in the night. Due to its finite speed, sunlight takes 8 minutes and 10 to 27 seconds to reach Earth, depending on the time of year. [1] The speed of light is the speed of electromagnetic waves. Light travels at slower speed inside materials like glass or water; its highest speed is in a vacuum.
