Plane Mirrors and Concave Mirrors
In this type of mirror, the image is upright and the same size as the actual object.
What is Plane Mirror?
A convex mirror reflects incoming light in this manner.
A) Converging (moves inwards)B) Diverging (spreads out)
What is B) Diverging (spreads out)?
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 the name for an image that appears on the other side of the mirror.
What is a virtual image?
This is the distance from a mirror is equal to half the center of curvature .
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?
What type of mirror always produces a virtual image that is upright and smaller?
What is a convex mirror?
In this type of image, light rays actually meet at the image, leading to the image being on the same side of the mirror as the object.
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?
This type of mirror is used in flashlights and lighthouses.
What is a concave mirror?
This type of mirror is used to enlarge viewing areas. Examples are magnifying glasses and security mirrors.
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?
Where does an object need to be in order for a virtual image to occur on a concave mirror?
What is in front of the focal point?
A real image created by a concave mirror is always...
A) Inverted
B) Upright
C) Smaller
D) Larger
What is A) Inverted?
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?
