The ratio of the longest wavelength to the shortest wavelength in Balmer series is $\frac{9}5$
The correct answer is option (D): The wavelength ranges of Lyman and Balmer series do not overlap
The dual nature of matter and the dual nature of radiation were throughgoing concepts of physics. At the beginning of the 20th century, scientists untangled one of the best-kept secrets of nature – the wave-particle duplexity or the dual nature of matter and radiation.
Electronic Emission
The least energy that is needed to emit an electron from the surface of a metal can be supplied to the loose electrons.
Photoelectric Effect
The photoelectric effect is a phenomenon that involves electrons getting away from the surface of materials.
Heisenberg’s Uncertainty Principle states that both the momentum and position of a particle cannot be determined simultaneously.
