The line perpendicular to the surface
What is the phenomenon where light bounces against a surface?
Reflection
What is the law governing the reflection of light?
The law of reflection
What is the term for the angle formed by the ray and the normal line?
Angle of reflection
What type of reflection occurs on a rough surface?
Diffused reflection
What is the term for the surface where light can bounce against?
Reflecting surface
What is the necessary condition for total internal reflection to occur?
The light ray moves from a denser medium to a less dense medium
What is the characteristic of reflected rays in regular reflection?
They have only one direction

What is the phenomenon responsible for the appearance of a water layer at short distances in a desert or on a road?
Mirage and Total Internal Reflection
Which of the following is NOT an example of total internal reflection?

What is the main advantage of using optical fibers in telecommunication?
Increasing signal speed
What is another application of optical fibers besides telecommunication?
Endoscopy
Test your understanding of the different types of reflection, including regular and diffused reflection, and the phenomenon of total internal reflection. Learn how light behaves when it interacts with smooth and rough surfaces, and how it travels between media of different optical densities.
