Plane Mirrors and Concave Mirrors
A convex mirror reflects incoming light in this manner.
What is spread out, or away from one another?
Diverging lenses refract incoming light in this direction.
What is outward, away from the principal axis.
This type of sight defect can be corrected by a converging lens.
What is farsightedness?
Light changes direction as it enters a transparent medium.
What is refraction?
This is an image in which no light rays actually pass through the image.
What is a virtual image?
This is the distance from a mirror is equal to half the center of curvature or radius of the mirror.
What is the focal length?
This property of a diverging lens allows you to determine the amount to which light is bent outward.
What is the curve of a diverging lens?
By altering this property of a converging lens, you can make the focal length smaller.
What is the curve of the lens?
The angle of incident ray to the normal striking a mirror will reflect at the same angle to the normal.
What is law of reflection?
In a concave mirror, light rays that are parallel to the principal axis are reflected through this single point.
What is the focal point?
In this type of image, light rays actually meet at the image.
What is real image?
Diverging lenses form this type of image.
What is a virtual?
The type of image formed when an object is between one and two focal lengths from a converging lens is _________, __________, and ___________?
What is an inverted, enlarged, and, real image?
The speed of light slows down when it enters a medium with a higher ____________.
What is index of refraction?
A real image created by a concave mirror is always
What is an upside down?
This type of mirror is used to enlarge viewing areas.
What is a convex mirror?
Diverging lenses produce images that are always virtual, __________, and ______________.
What is smaller and upright?
The type of image formed when an object is less than one focal length from a converging is _______, _________ and __________.
What is upright, enlarged, virtual image?
Light ray enters at an angle to a transparent medium with a lower index of refraction the light ray will bend _____________.
What is away from the normal?
This property of a concave mirror determines how far the focal point is from the mirror.
What is the curve of a concave mirror?
When an object is placed at this distance from a concave mirror, all light rays are reflected parallel to one another, creating a large, real image, very far away from the mirror.
What is at the focal point?
Diverging lenses are used to correct this type of sight defect.
What is nearsightedness?
The type of image formed when an object is more than two focal lengths from a converging lens is _________, ___________, and ___________.
What is an inverted, real image that is smaller than the object?
Light ray enters at an angle to a transparent medium and bends towards the normal because the speed of light is _____________.
What is slower?
