PHXII11:DUAL NATURE OF RADIATION AND MATTER

357564 Assertion :
Photoelectric effect is from metals of low atomic number while thermionic emission is from metals of high atomic number.
Reason :
The process of thermionic emission is temperature dependent, but photoelectric emission is independent of temperature.
