Reflection
What is reflection of light?
When light hits a surface and bounces back off, maybe changing direction
What is refraction of light?
When light goes through a medium and goes through, but changing direction
What happens during total internal reflection?
During total internal reflection, light reflects completely inside a material instead of passing through.
What does a converging lens do to light rays?
A converging lens brings light rays together at a point.
What is the relation between the angle of incidence and the angle of reflection?
They are equal
Why does light bend when it enters a different medium?
Light bends because its speed changes when it enters a different medium.
What is the critical angle?
The critical angle is the smallest angle at which total internal reflection can happen.
What does a diverging lens do to light rays?
A diverging lens spreads light rays apart.
Where is the image located in a plane mirror compared to the object?
The image in a plane mirror is located the same distance behind the mirror as the object is in front of it.
What is the refractive index?
The refractive index is a number that shows how much a material slows down light.
What happens to light when total internal reflection occurs?
When total internal reflection occurs, all of the light reflects back into the material.
What kind of image can a converging lens form?
A converging lens can form a real image or a virtual image depending on where the object is placed.
