X-rays are also known as:
Correct answer: B. Roentgen rays
- A. Rydberg rays
- B. Roentgen rays
- C. Ultraviolet rays
- D. Zig-zag rays
- E. Ruby rays
Explanation
The correct answer is Roentgen rays. X-rays were discovered by Wilhelm Conrad Roentgen in 1895, and in honour of his discovery, they are often called Roentgen rays. This discovery was pivotal in the development of diagnostic imaging in medicine. The other options are incorrect as they do not relate to the historical or scientific context of X-rays. Rydberg is associated with atomic spectra, ultraviolet rays are a different part of the electromagnetic spectrum, and 'zig-zag rays' and 'ruby rays' are not scientifically recognised terms related to X-rays.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.

The first theory about the structure of an atom was introduced by:
Rutherford concluded that central part of an atom is:
Figure shows the energy levels P, Q, R, S and G of an atom where G is the ground state. A red line in the emission spectrum of the atom can be obtained by an energy level change from Q to S. A blue line can be obtained by following energy level change.
For gaining atomic spectra, an evacuated glass tube is filled with:
During the production of x-rays, the cathode and anode are enclosed inside an evacuated glass chamber and a high DC voltage of the order of:
The transition of electrons should occur between which orbitals(n) will emit the longest wavelength in the Balmer series of Hydrogen.
