Science
is the branch that studies the behaviour of light.
Optics
what are the types of mirrors?
Plane Mirrors
Concave Mirrors (Converging Mirrors)
Convex Mirrors (Diverging Mirrors)
refract (or bend) light
lenses
what are the types of lenses?
Convex Lenses (Converging Lenses)
Concave Lenses (Diverging Lenses)
reflect light
mirrors
Produce a virtual image that is the same size as the object and is located as far behind the mirror as the object is in front of it
plane mirrors
Curved inwards. They can produce both real and virtual images, depending on the object's location
Concave Mirrors (Converging Mirrors)
Curved outwards. They always produce virtual, diminished, and upright images
Convex Mirrors (Diverging Mirrors)
Thicker in the middle than at the edges
Convex Lenses (Converging Lenses)
Thinner in the middle than at the edges
Concave Lenses (Diverging Lenses)
simplifies light by treating it as a straight line, called a "ray," moving in a specific direction.
Ray Model of Light
of a lens or mirror is a straight line passing through the centre of the lens or mirror.
Principal Axis
of a lens or mirror is a specific point where light rays either converge (come together) or appear to diverge (spread out) after interacting with the lens or mirror
Focus (Focal Point)
