Light (Optics) FAQs
Common questions and clear answers for this topic.
What is optics in physics?
Optics is the branch of physics that studies the behavior of light, including its reflection, refraction, and interaction with lenses and mirrors.
What is the difference between reflection and refraction?
Reflection is the bouncing back of light when it strikes a surface, while refraction is the bending of light as it passes from one medium to another with a different optical density.
What is a lens?
A lens is a transparent optical device with curved surfaces that refracts light to converge or diverge rays, commonly classified as convex (converging) or concave (diverging).
What is the speed of light?
The speed of light in a vacuum is approximately 3 x 10^8 meters per second, denoted by the symbol c.
What is total internal reflection?
Total internal reflection occurs when light traveling from a denser medium to a rarer medium strikes the boundary at an angle greater than the critical angle, causing it to be completely reflected back into the denser medium.
