The structure of solids is investigated by using

When $X$-rays from a Coolidge tube pass through an aluminum foil of thickness $0.3 \, mm$,$50\%$ of the $X$-rays are transmitted. If the potential difference between the target and the cathode is increased,the fraction of $X$-rays transmitted through the same foil will be .......

On increasing the number of electrons striking the anode of an $X-$ray tube,which one of the following parameters of the resulting $X-$rays would increase?

When $X-$rays pass through a strong uniform magnetic field,then they

$X$-rays are not used for radar purposes because:

In a Coolidge tube,the potential difference between the cathode and the anode is $120 \, kV$. What will be the maximum energy of the emitted $X$-rays?
