X-rays are invisible electromagnetic waves of high energy and short wavelengths lie between the wavelengths of gamma rays and the ultraviolet rays, Rontgen discovered invisible electromagnetic waves of short wavelength ranges from 10−13 m...
Quantum physics is the physics that allows us to study and explain scientific phenomena that might not be directly observed in our daily life especially when we deal with atomic and subatomic systems such...
On heating atoms of a pure elements – in gaseous or vapor state – to a high temperature or exposing them to a low pressure in an electrical discharge tube , they emit a...
The light refraction can be used in analyzing a beam of white light into its components of different wavelengths due to difference of the absolute refractive index according to the wavelength of the incident...
