Question

explain how x_rays produce an image of the bone on the film?

Answer 1

awell its in my physics text book that i read last year , and its dry theory so cant remember now

Answer 2

X-rays can penetrate through your skin but not through your bones..so its like a shadow of your bones on the film!

Answer 3

x rays have small wavelength, thus allow them to penetrate through the skin, they cannot be absorbed by the bone, their reflection produces an image on the screen...they have high frequency too

Answer 4

when a photon collides with an atom,the atom may absorb the photon's energy by boosting an electron to a higher level.for this to happen,the energy level of the photon has to match the difference in energy of the two electron positions.if not,the photon can't shift electron between orbitals.soft tissues of the body are made up of atoms with small energy difference between their orbitals.therefore they do not absorb x rays.larger atoms that make up our bones are more likely to absorb x ray photon because they have greater energy difference between their orbitals--the energy level more closely matches the energy of the photon.therefore calcium atoms which make up our bones are better at absorbing photons and this impression is projected onto a fluorescent screen.
