What is the wavelength of an x-ray photon with energy 8.0 kev (8000 ev)? (1 ev = 1.60 × 10−19 joule.)

what is its frequency?

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
