what is the relation between nanometer and meter
Nanometre The nanometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a metre (6991100000000000000♠0.000000001 m). The name combines the SI prefix nano- (from the Ancient Greek νάνος, nanos, "dwarf") with the parent unit name metre (from Greek μέτρον, metrοn, "unit of measurement"). It can be written in scientific notation as 6991100000000000000♠1×10−9 m, in engineering notation as 1 E−9 m, and is simply 1/7009100000000000000♠1000000000 metres. One nanometre equals ten ångströms. When used as a prefix for something other than a unit of measure (as in "nanoscience"), nano refers to nanotechnology, or phenomena typically occurring on a scale of nanometres (see nanoscopic scale).[1]
Iambic pentameter Iambic pentameter is the most common meter in English poetry; it is used in many of the major English poetic forms, including blank verse, the heroic couplet, and some of the traditional rhymed stanza forms. William Shakespeare used iambic pentameter in his plays and sonnets.
