Answer:
An interference pattern.
Explanation:
When we have two light source of the same frequency turned on close to each other, the light emitted by them will interfere since light is also a wave. This means that an interference pattern will appear in a screen put ahead of them, that is, bands of light and darkness where the waves are interfering constructively and destructively.
I believe it is a conductor I am learning this myself so I may be wrong
Answer:
2. a region about the nucleus in which an electron of specified energy will probably be found
Explanation:
With quantum mechanics we can find the wave function that describes the movement of the particles, the interpretation of this wave function is through the probability density (φ* φ).
This probabilistic interpretation of the energies, position and amounts of motion electrons allow us to find the region around the nucleus where an electron of specific energy can be found with a given probability.
The correct answer is 2
