Electromagnetic radiation is classified by wavelength or frequency. The electromagnetic spectrum includes (in order of decreasing wavelength): Radio waves, Microwaves, Infrared radiation, Visible light, Ultraviolet radiation, X-rays, and Gamma rays.
Visible light wavelengths are typically in the range of 400 nm to 700 nm.
Ultraviolet (UV) radiation has wavelengths shorter than visible light, usually in the range of 10 nm to 400 nm.
X-rays have even shorter wavelengths, generally ranging from about 0.01 nm to 10 nm.
Gamma rays have the shortest wavelengths, typically less than 0.1 nm.
Comparing the given options to the typical range of X-ray wavelengths (0.01 nm – 10 nm):
A) 500 nm falls in the visible light spectrum.
B) 5000 nm (5 µm) falls in the infrared spectrum.
C) 100 nm falls in the ultraviolet spectrum.
D) 1 nm falls within the typical range of X-ray wavelengths.
X-rays are high-energy photons commonly used in medical imaging (radiography, CT scans) and material analysis (X-ray crystallography, fluorescence). They are produced when high-speed electrons strike a metal target or by electron transitions in atoms.
