What is the effect of placing an object at the focal point of a concave mirror?
The reflected rays are parallel, and no image is formed.
What is the effect of a positive image distance () in the mirror/lens equation?
The image is real and inverted.
What is the effect of a negative image distance () in the mirror/lens equation?
The image is virtual and upright.
What is the effect of a positive magnification (M)?
The image is upright.
What is the effect of a negative magnification (M)?
The image is inverted.
What is the effect of |M| < 1?
The image is reduced.
What is the effect of |M| > 1?
The image is enlarged.
Define 'Principal Axis' of a spherical mirror.
The line through the center of the mirror and the center of curvature.
What is the 'Center of Curvature (C)' of a spherical mirror?
The center of the sphere from which the mirror is a part.
Define 'Focal Length (f)' of a spherical mirror.
The distance from the mirror to the focal point. It's half the radius of curvature: .
What is a 'Converging Lens'?
A lens that converges parallel light rays to a focal point on the far side.
Define 'Diverging Lens'.
A lens that causes light rays to diverge away from a focal point on the same side as the incident rays.
What is 'image distance' ()?
The distance from the image to the mirror or lens.
