Which of the following is an example of quantization?

Question

A. The amount of time spent in a classroom
B. The number of students in a classroom
C. Learning happening in a classroom
D. The temperature range in a classroom
I know I asked this question but I would this paragraph. Is it saying that b is true? I am so sorry I just what to understand the concept.

Quantization is the concept that a physical quantity can have only certain discrete values. Electrical charge, energy, light, angular momentum, and matter are all quantized on the microscopic level. They do not seem quantized on the macroscopic scale because the size of the steps between each possible value is so small. For example, matter is quantized because it is composed of individual particles that cannot be subdivided; it is not possible to have half an electron. Also, the energy levels of electrons in atoms are quantized. The electron's energy can have only certain values, and all intermediate values are prohibited. Mathematically this quantization arises from treating the electron's orbit as a standing wave, such that the orbit's circumference is equal a whole number of wavelengths.

Answer 1

I think the statement you have written (I assume a quote from your study guide) is very good and states the concept very plainly; however, I don't think it points the way to any of the choices. The quote also does a good job of repeating what I said before; i.e., that it is difficult to apply a microscopic concept to macroscopic events. I think you are right to want to understand the concept but I don't think answering this question one way or another is an indication that you understand or don't understand it. Sorry I can't be of more help.

Answer 2

I submitted the question and the correct answer was b. Thank you so much for helping me. I think the concept is just whole number. SInce you can't have a half of a student the answer was b.

Answer 3

b was your first choice a few days ago.
