Unit 10: Reflection, Nova- The Elegant Universe, Tesla, and Electricity Flashcards
plane mirror
flat mirror
concave mirror
a mirror that curves inward like a “cave”
convex mirror
a mirror that curves outward
incident ray
the reflection coming off an object and heading towards the mirror
sighting line
when you have a straight line going through a specified object
angle of incidence
the angle the reflection of an object hits a mirror at
angle of reflection
the angle at which an object “bounces” off a mirror, equal to the angle of incidence
orientation (inverted and erect)
how the image appears compared to the object
- inverted: upside down
- erect: right side up
reduced
the image is smaller than the object
enlarged
the image is bigger than the object
same size
the image is the same size as the object
center of curvature (C)
2F from the mirror
focal point (F)
lines of reflection intersect
optic axis
imaginary line through center of curve
image (real and virtual)
light rays intersect to make a visible picture
- real image: an image projectable onto a piece of paper or a screen
- virtual image: image seen by looking into a mirror or lens
