Answer 1

Revealing exciton dynamics in a small-molecule organic semiconducting film with subdomain transient absorption microscopy.
a) True
b) False
Answer - True

Answer 2

The questions deal with fundamental physics concepts such as wave-particle duality, current generation in a photoconductive cell, work function, the photoelectric effect, the resolving power of electron microscopes, polarization charging, and electromagnetic induction in a copper tube. Answers vary between true and false based on the concept.

Step-by-step explanation:

The questions listed are related to concepts in physics, particularly those concerning wave-particle duality, photoelectric effect, semiconductor physics, and electromagnetism. Here are the answers to some of the questions:

1. Wave-particle duality exists for microscopic particles like electrons and photons, but it is false that it exists for objects on the macroscopic scale.
2. It is true that a current is created in a photoconductive cell, even if only one electron is expelled from a photon strike.
3. The concept of a work function (or binding energy) is not permissible under the classical wave model, so this statement is false.
4. It is false that visible light is the only type of electromagnetic radiation that can cause the photoelectric effect; ultraviolet light is also commonly known to cause this effect.
5. Electron microscopes can indeed resolve images that are smaller than those resolved by light, making the statement true.
6. Charging an object by polarization does not necessarily require touching it with an object carrying excess charge, so this statement is false.
7. When you drop a bar magnet through a copper tube, it indeed induces an electric current in the tube due to electromagnetic induction, so the statement is true.
