1Spherical mirror/ curved mirror
has a reflecting surface taken from the surface of a sphere.
2what are the two types of spherical mirror?
concave and convex mirror.
3what is convex mirror?
- curves inward in the direction of the incident ray.
- curves outward in the direction of the incident ray.
- none of the above.
4What is concave mirror?
- curves inward in the direction of the incident ray.
- curves outward in the direction of the incident ray.
5Explain plain mirror using the LOST
behind, upright,same size, virtual
6Center of the mirror or sometime called pole in the mirror.
Vertex
7The center of sphere.
Center of curvature
8Focal point mean
A ray parallel to tha principal axis are brought to a single point.
9focal length
The distance of the focus from the vertex or center of curvature.
10A normal line draw from the vertex of the mirror.
Principal axis
11The distance from the vertex to the center of curvature is called_?
radius R of curvature
12What is the meaning of LOST?
- local, original, sample,time
- land, orientation, sheet, technique
- location, orientation,size,type
13Recite the parts of the spherical mirror.
Vertex, Center of curvature, Focal point, focal length, Principal axis.
