Question

Multiple photoelectric effect experiments were conducted by applying a variety of visible wavelengths to a metal surface and recording the electrical current produced.
Data from these experiments provided evidence for which of the following claims?

• A. Electromagnetic radiation exhibit wave-like characteristics.
• B. Electromagnetic radiation exhibit particle-like characteristics.
• C. Electrons have quantized energies in an atom.
• D. Electrons behave like waves in an atom.

Answer 1

The correct option is A Electromagnetic radiation exhibit wave-like characteristics.

The photoelectric experiments conducted gave solid evidence stating electromagnetic radiation (EMR) has wave nature this was contradictory to the fact EMR has particle nature but the wave nature was explained by these experiments. Hence answer is option A.
