Telecоmmunicаtiоns relies оn opticаl trаnsmission of signal using fiber optics and diode lasers. Shown below are some specific regions of the electromagnetic spectrum used for communications. if you wanted to use the middle off the "E band", you would use a wavelength of 1410 nm. What bandgap energy would you need in a semiconductor to build a diode laser that will operate at this wavelength? Calculate the bandgap energy in units of kJ/mol, to one decimal place. You can use the following equation, with appropriate unit conversions: E = h c / λwhere:λ = wavelengthh = Planck constant, 6.626 × 10-34 J⋅sc = speed of light, 2.998 × 108 m⋅s-1Avogadro's number, Na = 6.022 × 1023 Remember that the Planck constant refers to a single "molecule" or single optical transition
