Q: What is visible light?
It is electromagnetic radiation that is visible to the human eye and responsible for the sense of sight.
Q: What is the wavelength range of visible light?
It ranges from about 389 nanometers to about 749 nanometers.
Q: What are the primary properties of visible light?
Intensity, propagation direction, frequency or wavelength, spectrum, and polarization.
Q: What is the speed of visible light in a vacuum?
299,792,458 meters per second, which is one of the fundamental constants of nature.
Q: What are photons?
They are tiny packets in which visible light, as well as all types of electromagnetic radiation, are emitted and absorbed.
Q: What is the wave-particle duality of visible light?
Visible light exhibits properties of both waves and particles.
Q: What is optics?
It is the study of light, which is an important research area in modern physics.
Q: What is the primary source of light on Earth?
The sun, which emits about 44% of the electromagnetic radiation that reaches the ground in the visible light range.
