Study Points

Key Equations

Ratio of focal length to lens diameter
f stop   =   f D Indicates shutter speed required for exposure
Magnification at N (usually 25cm) M   =    N f   +   1 Magnification perceived by single-lens magnifying glass for relaxed human eye
Telescope magnification M telescope   =   f objective f eyepiece Magnification achieved by Keplerian telescope.
Microscope magnification M microscope   =   M objective M eyepiece   = (   N f eyepiece   )   (   l   f eyepiece d object )
Magnification achieved by compound microscope
