Light Behaviour
What type of material does not let light pass?
Opaque
Incident Ray.
What is a plane mirro?
An extremely flat, reflective surface.
What happens to light rays in a concave mirror?
They converge at a focal point.
What is a lens?
A transparent object that causes light to refract and has at least one curved side.
What type of material lets some light pass?
Translucent.
The ray that leaves the mirror is called the:
Reflected ray
What is a virtual image?
An image formed behind the mirror due to the extended rays.
What happens to light in a convex mirror?
It diverges in different directions.
What does a converging lens look like?
- Has one or two convex surfaces
- Thicker in the center.
What material lets almost all light pass?
Transparent.
The line between the incident and reflected ray is called the:
Normal
What is a real image?
It is formed in front of the mirror where reflected rays meet.
Name 3 characteristics of light in a convex mirror.
- smaller than object
- virtual
- upright
- closer to the mirror than the object
- distorted
What does a diverging lens look like?
- One or two concave surfaces
- Thinner in the centre.
What cause a pencil to look as if it is bending in a glass of water?
Refraction.
Define reflection.
When light bounces off of an object and goes in the opposite direction.
What is a mirror that curves inward called?
Concave.
Name 3 characteristics of images in a concave mirror when an image is located far from the focal point.
- smaller
- inverted
- real image
- closer to the mirror than the object
What happens to light that passes through a converging lens?
Rays refract toward the normal, focusing on a single point.
What is it called when no light enters something and is trapped there?
Absorbed.
Name 3 characteristics of images in concave mirrors when the object is located between the focal point and the mirror.
- larger
- upright
- virtual
- farther from the mirror
What is a mirror that curves outward called?
Convex.
Name 3 characteristics of images in concave mirrors when the object is located close to the focal point.
- larger
- upright
- real
- farther from the mirror than the object
What happens when light leaves a diverging lens?
The rays refract away from the normal.
