Which off the following is the smallest unit?
Micron , fermi , millimeter.
Explain also.
Answers
MILLIMETER IS THE ANSWER.....
Conversion between metric and English units
➡️1 meter (m) = 39.4 inches = 1.09 yards; 1 yard = 0.92 m.
➡️1 centimeter (cm) = 0.39 inches; 1 inch = 2.54 cm.
➡️1 millimeter (mm) = 0.039 inch = 39/1,000 inch; 1 inch = 25.4 mm.
➡️1 micrometer or micron (um) = 0.000039 inch = 39/1,000,000 inch;
➡️1/1000 inch = 25.4 um.
hey hooda how are u
a millimeter is 10^-3 m, and is about the size of a mite.
an angstrom is 10^-10 m, and is crudely on the same order of magnitude as the size of an atom.
a Fermi is the smallest of three at 10^-15 m (also called a femtometer), and its length roughly describes the scale of atomic nuclei (hence it is named after the nuclear physics pioneer Enrico Fermi).

Fermi level energy is the energy level above which probability of finding an electron is 0 at 0k.
I.e all the electrons have energy less than the Fermi level energy at 0k.
No electron exist above Fermi level at 0 k.
But as the temperature rises electrons can be found above the Fermi level.
Fermi level is the energy level lies somewhere between conduction band and valence band and it's position between both the band is decided by Donar and accepter impurities I.e wheather it is p type or n type.
