Which of the following is incorrect for `X` rays (Roentgen rays)?

Options

A. They are produced when a stream of electrons strikes a heavy metal traget forming part of a massive anode.
B. They are deflected by the electric and megnetic fields.
C. They are of very short wavelengths `(~0.1 nm)` and posses electromagnetic character.
D. The absorption of the rays by matter depends upon the density and the relative atomic mass (r.a.m.) of the material. The lower the r.a.m. and density, the more transparent is the material to `X` rays.

Answer

B

Explanation

These rays cannot be deflected by an electric and a magnetic field because they are not composed of charged particles.
