Question

4) Which one of the following is considered to be ionizing radiation? A) visible light B) radio waves C) X-rays D) microwaves E) infrared radiation

Answer 1

Answer: C) X-rays

. Order of energy in energy spectrum: Radio wave < Microwave < Infraved < Visible light Luv < x-ray & Gamma Jonizing radiation is the radiation with enough energy to remove the tightly bound electrons from the orbit of an atom resulting in the ionization of the atom. This mergy required will fall in the un region, &. radio waves, microwaves, infrared radiation and visible light, having less energy than ux, is not considered to be ionizing radiation whereas x-rays, with energy higher than un, is considered to be ionizing radiation.
