हिन्दीGiven below are two statements: Statement I: The energy of a quantum of radiation is proportional to its frequency. Statement II: The photoelectric emission of electrons from a metal surface shows a time lag after the light beam strikes the surface. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Statement I is correct but Statement II is incorrect.
Explanation
Statement I is correct (\( E = h\nu \)). Statement II is incorrect because photoelectron emission is instantaneous with zero time lag.
