bcz x rays have very very small wave length.....

Ans: X-rays are diffracted by crystal because wave length of X-rays and interplanar spacing in the crystals is of the same order, (angstrom, Ã…), so it satisfies Bragg condition for diffraction

2dsinθ= nλ

Where n is the integer and determined by the order given, λ is the wave length of the x-rays, d is the spacing between the planes in the atomic lattice, and θ is the angle between the incident ray and the scattering planes (diffracted angle).

Are the x rays behaves like visible light or not?

Yes, but x-rays can't be focused by lenses, they just pass through the lens. They can only be focused by glancing angle nested cylinder mirrors. X-rays pass through most things.

What will happen to the structure of aluminium foil while x-rays pass through it?

X-rays have high energy and can penetrate aluminum foil easily due to its low atomic number. As X-rays pass through aluminum foil, they will interact with the atoms and may be absorbed or scattered. Overall, the structure of aluminum foil will remain largely unchanged as X-rays pass through it.


What absorbs X-rays most effectively?

X-rays cannot pass through lead, and lead is what is used in X-ray shielding.

Yes, beryllium is transparent to x-rays; windows of x-rays tubes are made from a thin foil of beryllium.


Why U.V. rays does not go through metals?

The short answer is that the photons are not energetic enough. Photons of x-rays and gamma rays are energetic enough to pass through metal.


Why are x rays powerful?

X-rays are a radiation which is above communications radio waves and below gamma rays. It is a highly energetic radio wave which is why it is able to pass through some materials. It is not energetic enough to pass through highly dense materials such as lead.
