exactly what wavelengths can be found in the device’s emission range? The permitted energies of a quantum system tend to be 0.0 eV, 5.0eV , and

8.5eV. In nm please

whenever change occurs from 8.5eV to 0

eV

after that = 8.5 eV – 0

eV = 8.5 eV = 8.5 x 1.6 x 10-19 J

the wavelength regarding the photon are provided as ::

placing the values

= 6.63 x

10-34 x 3 x 108 / (8.5 x 1.6 x

10-19 J) = 19.89 x 10-26 / 13.6 x

10-19

= 1.4625 x

10-7 = 146.25 nm

whenever change occurs from 5 eV to 0

eV

after that = 5 eV – 0

eV = 5 eV = 5 x 1.6 x 10-19 J = 8 x 10-19

J

the wavelength regarding the photon are provided as ::

placing the values

= 6.63 x

10-34 x 3 x 108 / (8 x 10-19 J) =

19.89 x 10-26 / 8 x 10-19

= 2.48625 x

10-7 = 248.625 nm

whenever change occurs from 8.5 eV to 5

eV

after that = 8.5 eV – 5

eV = 3.5 eV = 3.5 x 1.6 x 10-19 J = 5.6 x

10-19 J

the wavelength regarding the photon are provided as ::

placing the values

10-34 x 3 x 108 / (5.6 x 10-19 J)

= 19.89 x 10-26 / 5.6 x 10-19

= 3.5518 x

10-7 = 355.18 nm
