It's urgent please solve quickly. 3. Three infinite quantum wells, A, B and C are in a structure with the well widths as 5 nm, 10nm and 15 nm. The lowest energy levels of each are E., Es and E.(a) Write down the ratio of the n=1 energy level of the three wells as E.: Es: E, in order ofthe highest energy to the lowest.(b) If the material was a direct band gap semiconductor which well would emit light with thelongest wavelength? Write the wavelengths Aa, Ag and Ac of emission of light A,> A>A, in theorder of longest to the shortest in terms of Aa, Ag and Ac.

(a) The energy of the particle of mass m in the nth energy state of infinite well of width L is…

Three infinite quantum wells, A, B and C are in a structure with the well widths as nm and 15 nm. The lowest energy levels of each are EA, E, and E.. (a) Write down the ratio of the n=1 energy level of the three wells as EA: Ea: E, in the highest energy to the lowest. (b) If the material was a direct band gap semiconductor which well would emit lig longest wavelength? Write the wavelengths Aa, Aa and Ac of emission of light A,> order of longest to the shortest in terms of A, Ag and Ac.
