The wavelength of X-Rays as compared to normal light is

X-rays and visible light (normal light) are both forms of electromagnetic radiation, but they occupy different regions of the electromagnetic spectrum. In this spectrum, wavelength is inversely proportional to frequency and energy. Visible light has wavelengths ranging from approximately 400 nm to 700 nm. In contrast, X-rays possess much higher energy and higher frequencies, resulting in significantly shorter wavelengths, typically ranging from 0.01 nm to 10 nm.

Therefore, X-rays always have a shorter wavelength than normal light. Option D is incorrect because the wavelength is a fundamental property of the radiation type itself and is not determined by the physical size of the generating machine.
