Why is the wave nature of matter not more apparent to our daily observations?

Assertion : Photoelectric effect demonstrates the wave nature of light. Reason: The number of photoelectrons is proportional to the frequency of light.

Assertion: Photoelectric effect supports the quantum nature of light. Reason : Electric charge of photoelectrons is quantised.

Assertion : Photoelectric effect supports the quantum nature of light. Reason : Photoelectric emission is instantaneous.

The wave nature of matter is not observed in daily life because their wave length is

Why photoelectric effect cannot be explained on the basis of wave nature of light? Give reasons.

the photoelectric effect can not be explained by the wave theory of light because:

Assertion: Photoelectric effect proves the particle nature of light. Reason: Photoemission starts as soon as light is incident on the metal surface, provided frequency of incident light is greater than or equal to the threshold frequency.

Assertion : The threshold frequency of photoelectric effect supports the particle nature of light. Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.
