level questions: Level 1 of Reflection at Curved Mirrors

Question	Answer
Types of mirrors	Plane mirrors and curved mirrors
Infinite radius, zero curvature, all normals are parallels, and magnification is unity	Plane mirrors
Finite radius, finite curvature, normals are not parallel, and magnification is variable	Curved mirrors
The longer the curve, the lesser the radius	True
Types of curved mirrors	Aspherical mirror and spherical mirror
Surface is not surface of a sphere	Aspherical mirror
Normals do not pass thru a single point or the center of curvature	Aspherical mirror
Types of aspherical mirror	Paraboloidal, ellopsoidal, and cylindrical
Surface is a portion of a sphere	Spherical mirror
All normals pass thru a single point or the center of curvature	Spherical mirror
Types of spherical mirror	Concave mirror and convex mirror
The reflecting surface is the inner portion of the sphere	Concave mirror
Converges light from infinity after reflection	Concave mirror

Where the reflection of light actually happens	Aperture
Gives the size of the mirror	Aperture
Midpoint of the vertex	Pole
The point in the center of the mirror	Center of curvature
