Reflection Simulation

Real image and virtual image Looking at an object, we feel there is an object in it. By the way, if you feel that there is something, we say there is an ‘image’, even if there is no real object...

Why is the incident angle and the reflection angle the same? ‘Law of reflection’ has the word ‘law’ attached. ‘Law’ refers to a situation in which a natural phenomenon happens repeatedly and without exceptions. In other words, ‘law’ only tells...

The law of reflection Consider a light-ray incident on a plane mirror, the angle of reflection is equal to the incidence angle. This is the law of reflection. When looking at the end of the head and feet with a...

Total reflection and critical angle When light enters from a medium with a large refractive index to a medium with a small refractive index, the incident light does not pass through the boundary surface but is reflected at all. When...

What is an image? Our eyes are designed to sense where the light came from. Even if the light didn’t actually originate there, if our eyes feel that way, our eyes say there’s an image there. When two mirrors face...
