Photons are elementary particles that make up light. They originate from various sources such as the sun, stars, and other celestial bodies. They can also be created artificially through processes such as fluorescence and nuclear reactions.
No, photons are massless particles. They only have energy and momentum, which are related to their frequency and wavelength. This is why they can travel at the speed of light.
Photons travel in a straight line at the speed of light. They can also be affected by gravity and can be bent by massive objects, as demonstrated by Einstein's theory of general relativity.
Yes, photons can be absorbed or scattered by matter, which can change their energy or direction. However, their energy is always conserved, so they are not truly destroyed.
Photons play a crucial role in many aspects of science, including optics, quantum mechanics, and astrophysics. They also have practical applications in technology, such as solar panels and lasers. Understanding photons has led to groundbreaking discoveries and advancements in various fields.
