Question: Assume that lasers are available whose wavelengths can be precisely tuned to anywhere in the visible range-that is, in the range 450 nm <

Assume that lasers are available whose wavelengths can be precisely "tuned" to anywhere in the visible range-that is, in the range 450 nm < λ < 650 nm. If every television channel occupies a bandwidth of 10 MHz, how many channels can be accommodated within this wavelength range?
