Hope it helps u

Answer 2

Out of these 4 option blue monochrome light offers highest frequency. It is 620–680 THz in terms of frequency, 450–485 nm in terms of wavelength, and 2.64–2.75 eV in terms of photon energy.

Visible spectrum of human eye largely depends on these factors and that is the reason, out of 4 given options blue monochrome light can be seen from higher distance.
