An electromagnetic wave is found to have a wavelength of the order of 1 ( 10⁻¹⁰ m ). Identify the electromagnetic wave and the standard method used to produce it.

Options

  1. AX-rays; produced by bombarding a metal target with high energy electrons.
  2. BGamma rays; produced by the radioactive decay of the nucleus.
  3. CUltraviolet rays; produced by special lamps and very hot bodies.
  4. DX-rays; produced by the vibration of atoms and molecules.

Correct answer

A. X-rays; produced by bombarding a metal target with high energy electrons.

Step-by-step solution

The wavelength of 1 ( 10⁻¹⁰ m ) falls in the characteristic range of X-rays, which typically span from 10⁻⁸ m to 10⁻¹³ m . According to the electromagnetic spectrum, X-rays are commonly produced by bombarding a metal target with high energy electrons. Gamma rays generally have even shorter wavelengths and are of nuclear origin. Ultraviolet rays have longer wavelengths ( 10⁻⁸ m to 4 10⁻⁷ m ). The vibration of atoms and molecules produces infrared waves, not X-rays. Answer: X-rays; produced by bombarding a metal targ
