Question

Give the wavelength range of X-rays.

Answer 1

Hint: X-rays was first discovered by German physicist Wilhelm Konard Roentgen in the year 1895, while investigating the effects of electron beams in the cathode ray tubes. Their wavelengths are very small and far from the visible region. They have high frequencies. They are commonly produced during acceleration or deceleration of charge particles.

Complete step by step answer:
X-rays are a very small part of the electromagnetic spectrum. Their wavelength range is around $10^{-8}m$ to $12^{-12}m$ and frequency of $10^{16}$ to $10^{20}Hz$. These can again be classified as soft and hard X-rays and gamma rays. Clearly, their wavelengths are very small, far from the visible region and they have high frequencies. They are commonly produced during acceleration or deceleration of charge particles.

X-rays were first discovered by German physicist Wilhelm Konard Roentgen in the year 1895, while investigating the effects of electron beams in the cathode ray tubes. The discovery of X-rays later led to the discovery of radioactive metals, and their study called radioactivity.

These are used to study the cells in the body, due to their high penetration powers. They also have high ionization energy, which causes them to eject electrons from a neutral atom. They are also used to combat the growth of tumours.
Hence the answer is $10^{-8}m$ to $12^{-12}m$

Note:
X-rays are a very small part of the electromagnetic spectrum. The spectrum also includes radio waves, microwaves, infrared, optical, ultraviolet, and gamma-rays. Due to the high ionising and penetrating power of X-rays it is best to avoid unnecessary exposure to them as they result in mutation of the chromosomes for humans.
