Take the difference among your experimental value and your known value, and divide that difference by your know value.Say you experimentally found the force of gravity to be 8m/s2, and you know that the true/known value is 9.8 m/s2, the percent error would bel 8 - 9.8 l / 9.8= 0.1836 or 18.36%
If a hydrogen atom in its ground state absorbs a photon with a wavelength of 93 nm, it jumps to an excited state. What is the value of the energy in that excited state?
(a) Distinguish among metals, insulators and semiconductors on the basis of their energy bands. (b) Why are photodiodes used preferably in reverse bias condition? A photodiode i
