Question

state any four properties of x-rays

Answer 1

X-rays form part of the electromagnetic spectrum. Their properties make them very useful in medicine. The detailed images they provide help to diagnose disease, while radiography uses high-energy X-rays to treat cancer. However, X-rays are hazardous so appropriate precautions must be taken to protect medical staff and patients from harmful effects.
Properties of X-rays
X-rays are electromagnetic waves and part of the electromagnetic spectrum.

As with visible light and other electromagnetic waves, X-rays transfer energy and are transverse waves (their oscillations are perpendicular to the direction of energy transfer).

X-rays also have these properties:

they have a very short wavelength (about the same size as the diameter of an atom

they cause ionisation (adding or removing electrons in atoms and molecules)

they affect photographic film in the same way as visible light (turning it black)

they are absorbed (stopped) by metal and bone

they are transmitted by (pass through) healthy body tissue

These properties make X-rays very useful for medical diagnosis and treatment.

Answer 2

1.They have very short wave lenght
2.They cause ionisation
3.They effect photographic film in the same way as visible light
4.They are absorbed by metal and bone
