Properties and Uses of X-rays

Consider a photon of continuous $\mathrm{X}$-ray and a photon of characteristic $\mathrm{X}$-ray of the same wavelength. Which of the following is/are different for the two photons ?

$\mathrm{X}$-ray incident on a material

Suppose a monochromatic X-ray beam of wavelength $100 \mathrm{pm}$ is sent through Young's double-slit and the interference pattern is observed on a photographic plate placed $40 \mathrm{cm}$ away from the slit. What should be the separation between the slits so that the successive maxima on the screen are separated by a distance of $0.1 \mathrm{mm}$?

The stopping potential in a photoelectric experiment is linearly related to the inverse of the wavelength $\left(\frac{1}{\lambda }\right)$ of the light falling on the cathode. The potential difference applied across an X-ray tube is linearly related to the inverse of the cutoff wavelength $\left(\frac{1}{\lambda }\right)$ of the X-ray emitted. Show that the slopes of the lines in the two cases are equal and find its value.

Visible light passing through a circular hole forms a diffraction disc of radius $0.1 \mathrm{mm}$ on a screen. If X-ray is passed through the same set-up, the radius of the diffraction disc will be

$50\%$ of the X-ray coming from a Coolidge tube is able to pass through a $0.1 \mathrm{mm}$ thick aluminium foil. The potential difference between the target and the filament is increased. The thickness of aluminum foil, which will allow $50\%$ of the X-ray to pass through, will be

$50\%$ of the X-ray coming from a Coolidge tube is able to pass through a $0.1 \mathrm{mm}$ thick aluminium foil. If the potential difference between the target and the filament is increased, the fraction of the X-ray passing through the same foil will be

X-ray beam can be deflected

Why is exposure to X-ray injurious to health but exposure to visible light is not when both are electromagnetic waves?

Characteristic X-rays may be used to identify the element from which they are coming. Can continuous X-rays be used for this purpose?

Can X-rays be used for photoelectric effect?

X-ray and visible light travel at the same speed in a vacuum. Do they travel at the same speed in the glass?

Can X-rays be polarized?
