The fig. represents the observed intensity of X-rays emitted by an X-ray tube as a function of wavelength. The sharp peaks A and B denote

Options

A. Band spectrum
B. Continuous spectrum
C. Characteristic radiations
D. White radiations

Answer

C

Explanation

X–ray spectra, depends on accelerating voltage and target element.
We can find sharp peaks super imposed on continuous spectrum. These are at different wavelengths for different elements. They form characteristic X-ray spectrum.
