Spherical Mirrors Flashcards
1
Q
The line u draw to the curve
A
Tangent line
2
Q
A ray coming on to the mirror parallel to the axis
A
Paraxial ray
3
Q
The center of the sphere the mirror is cut from
A
Center of curvature (c)
4
Q
The point at the center of the mirror
A
Vertex (v)
5
Q
The radius of the sphere the mirror is “cut from”
A
Radius of curvature
6
Q
The point where rays from a distance appear to converge
A
Focal point
7
Q
TRUE OR FALSE
focal point is halfway between the surface and the center of curvature
A
True
8
Q
Spherical mirrors are drawn in…
A
Two dimensions
9
Q
Special rays for locating the image formed by a spherical mirror
A
- Ray passing through the center of curvature snd going back (reflecting itself)
- Ray parallel to the optical axis and reflected to the focus
- Ray passing through the focus then reflected parallel-y
- Ray striking the vertex then reflecting equally like the incidence
10
Q
Plane mirror properties:
A
Virtual (behind the mirrors)
Upright
The same distance from the mirror as the object
Same size as the object
11
Q
Mirrors cut out of a spherical reflecting surfac
A
Spherical mirror
