Find the change in the fraction of visibility for a person from planet Krypton with x-ray vision in addition to visible spectrum.
The human eye is sensitive to what fraction of the electromagnetic spectrum, assuming a spectral a special range of 10^4 to 10^20 Hz? If we came from the planet Krypton and had X-ray vision (that is, if our eyes were sensitive to X rays in addition to visible light), how would this fraction be change?
