Consider the following statements with reference to X-rays:
1. They produce heat when absorbed by matter.
2. They are generated when fast-moving electrons strike a metal target.
3. They can penetrate through a thin sheet of aluminium.
Which of the statements given above are correct?

Which of the statements given above are correct?
The correct option is A 1,2 and 3
The following statements are reference to X-rays:
1. They produce heat when absorbed by matter. : X-ray
beam attenuation. As the x-ray beam passes through tissue, photons get absorbed
so there is less energy; this is known as attenuation. It turns out that higher
energy photons travel through tissue more easily than low-energy photons (i.e.
the higher energy photons are less likely to interact with matter).
2. They are generated when fast-moving electrons strike a
metal target.: An electromagnetic wave called x-ray is produced when fast
moving electrons impact on high atomic weight substances. However, when these
fast moving electrons strike on a metal target, a photoelectric effect occurs.
3. They can penetrate through a thin sheet of aluminium.
: X-Rays will Pass Straight through Aluminium of Almost ANY Thickness as it's
Density is so Low !! But the Crystalline Structure of Diamond makes it Totally
Opaque to X-Rays !! X-Rays do not "see"! But yes, they can pass
easily through a single sheet of aluminum foil.
