Document Summary

Microorganisms range in size from the smallest (viruses) measured in nanometers (nm), to the. Common units of measurement: centimeter (cm) = 10-2 meter or 0. 394 inches, millimeter (mm) = 10-3 meter, micrometer (um) = 10-6 meter, nanometer (nm) = 10-9 meter, angstrom ( ) = 10-10 meter. Lenses & the bending of light: light is refracted (bent) when passing from one medium to another, refractive index. A measure of how greatly a substance slows the velocity of light: direction and magnitude of bending is determined by the refractive indices of the two media forming the interface (ie. , glass and air) Glass has a higher refractive index than air. Lenses: focus light rays at a specific place called the focal point, distance between center of lens and focal point is the focal length, how lenses bend light (right diagram) F = focal point f = focal length. The strength of the lens is related to the focal length.
