NEET Physics (general) MCQ Question
Which combination of statements about the dual nature of matter and radiation is correct?
The photoelectric effect demonstrates the particle nature of light; high frequencies can eject electrons, while low frequencies cannot.
All objects, regardless of their mass, exhibit significant wave properties; hence, macroscopic objects show clear wave behavior.
The energy of a photon is directly proportional to its frequency; lower frequency light has higher energy photons.
The de Broglie wavelength of an object is inversely proportional to its momentum; heavier objects exhibit longer wavelengths.
Correct Answer
Detailed Explanation
The photoelectric effect indeed shows that only light of a frequency above a certain threshold can eject electrons, confirming the particle nature of light. Low frequency light does not have enough energy to overcome the work function, hence no electrons are emitted.
