What wavelengths appear in the system’s emission spectrum?

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
= 6.63 x
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
