Mirror Flashcards
(25 cards)
a smooth reflecting surfaces, usually made up of polished metal or glass that has been coated with some metallic substance
reflects whatever is infront of it
mirror
light will just pass thru it
aluminum
the reflected light causes an _____ to be formed
image
reflection of light in a smooth substance*
images are formed when _____ strikes a reflecting surface such as mirror or lens
light
the actual source of incident rays
object
what you see in the mirror
formed by reflected rays
image
ray of light that strikes the surface
incident rays
mirrors can produce images that can be projected on screen
occurs when light rays actually intersect at the image
always inverted
real image
produce images that cannot be projected on screen
occurs when light rays do not actually meet at the image
virtual image
a flat mirror that reflect light rays in the same way that they approach the mirror
same amount of incident rays, same amount of plane mirror
what you see is what you get
always the same distance behind the mirror as the object is in front of the mirror
plane mirror
second class of mirror in a form of spherical mirror
curved/spherical mirror
converging mirror where light rays that strike the mirror surface are reflected so they “converge” or “come together” at a point
concave
a diverging mirror where the light rays that strike the mirror surface are reflected so that they “go apart” and they never come to a point
convex
what are u gona consider in tracing image in mirrors?
type of mirror
size
location
the center of the circle of which the mirror represents a small arc
center of curvature
where parallel light rays converge; always found at the inner part of the circle of which the mirror is a small arc
focus
where the mirror crosses the principal axis
where the principal is passing thru
vertex point
line drawn thru the vertex, focus and the center of curvature of the mirror upon which the object rests
principal axis
distance from the focus to the vertex of the mirror
focal length
the distance from the center of curvature to the vertex of the mirror; it corresponds to the radius of the circle
radius of curvature
how to describe the image formed?
SALT
size
attitude
location
type
in comparison to the original object. is it the same size, smaller or bigger?
size
which way the image oriented compared to the original?
attitude (upright or inverted)
in front or behind
location
