Photoelectric Effects and deBroglie Equation: Practice Problem & Solution

In which of the following, emission of electrons does not take place (1990)
Thermionic emission
X-rays emission
Photoelectric emission
Secondary emission

Solution Explained:

To solve this problem, we apply the core principles of Photoelectric Effects and deBroglie Equation. Understanding the underlying formula is key to arriving at the correct answer below:

X-ray emission involves the release of high-energy electromagnetic radiation (photons) when fast-moving electrons strike a heavy target, not the emission of electrons. The other processes all involve electron emission.
