Final answer:
The statement concerning phenomena only associated with edge dislocations is false. Dislocations refer to irregularities in a crystal's structure and include edge and screw dislocations. Edge dislocations do not have a monopoly on phenomena in material sciences.
Step-by-step explanation:
The statement "Phenomena only associated with edge dislocations" is false. Dislocations in materials science are irregularities within the crystal structure, and they can be of two main types: edge dislocations and screw dislocations. Each type has associated phenomena, but not all phenomena are exclusively associated with edge dislocations.
For example, wave-particle duality is not a phenomenon associated with edge dislocations at all; it is a fundamental concept in quantum mechanics that applies to microscopic particles like electrons and photons, indicating that they exhibit both wave-like and particle-like properties. This concept is false when applied to macroscopic objects.
Regarding electromagnetic radiation and its interactions with matter, it's false to claim that visible light is the only type that can cause the photoelectric effect - ultraviolet light and other higher energy radiations can also cause this effect.
Furthermore, the interaction between waves, such as the principle that the amplitude of one wave is affected by another only when they are precisely aligned, is actually false. Waves can interfere in various ways depending on their phase relationship, leading to either constructive or destructive interference.
Additionally, it is true that the electric-field lines from a positive point charge spread out radially and point outward, and it is also true that a current is created in a photoconductive cell with just one expelled electron post photon strike. The concept of a work function is not consistent with the classical wave model of light, thus it is false that it is permissible under this model. Lastly, it is true that the two types of interference are constructive and destructive.
