Reflection
What is reflection?
This happens when light bounces off a surface instead of passing through it.
What is refraction?
This is the bending of light when it passes from one medium to another.
What is total internal reflection?
This happens when light reflects completely inside a medium instead of refracting out.
What is a diverging lens?
This type of lens spreads light rays apart.
What is the Law of Reflection?
This law states that the angle of incidence is equal to the angle of reflection.
What is a denser medium?
Light slows down and bends toward the normal when entering this type of medium.
What is the critical angle?
This must be exceeded for total internal reflection to occur.
What is a converging lens?
This type of lens brings parallel light rays to a focal point.
What is diffuse reflection?
This type of reflection happens on rough surfaces and scatters light in many directions.
What is Snell’s Law?
This law relates the angles of incidence and refraction using refractive indices.
What are fiber optic cables?
This device uses total internal reflection to transmit light signals over long distances.
What is the lens formula?
(1/f = 1/v + 1/u)
