Which of the following is an example of quantization?
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
What is the definition of quantization
if apex . answer is B
Quantization is the process of representing continuous values or variables in a discrete form. It involves dividing a continuous or analog signal into a set of discrete levels or values. This is done by assigning discrete numerical values to represent the continuous signal.
In the context of the given options, quantization would involve representing a continuous variable or value in a discrete form. Let's evaluate each option to identify the example of quantization:
A. The amount of time spent in a classroom: This is not an example of quantization. Time spent in a classroom can be measured continuously and is not typically represented in discrete levels.
B. The number of students in a classroom: This is an example of quantization since the number of students can be represented as discrete levels. For example, you could have 10 students, 15 students, or 20 students, which are discrete values.
C. Learning happening in a classroom: This is not an example of quantization. Learning is a concept that is difficult to quantify or represent in discrete levels.
D. The temperature range in a classroom: This is not an example of quantization. Temperature can be measured continuously and is not typically represented in discrete levels.
Therefore, the correct answer is B. The number of students in a classroom is an example of quantization.
The one electron in the H atom is in the n = 1 shell in its ground state. It can be moved from the n = 1 shell to n = 2 or n = 3 or n= 4 etc by absorbing energy. Thus we can expose H atoms to energy and cause the electron to move to higher levels BUT not just any amount of energy will do. In order to move the electron from n = 1 to n = 2 it requires what I will call x amount of energy. If the energy we are using is too small nothing happens; i.e., there isn't enough energy to move the electron to n = 2 shell. But also nothing will happen if the energy is just slightly more than enough to move it to n = 2. The electron moves when just the right amount of energy, what I call a packet of energy, is absorbed. If that packet (a quantum of energy also called a photon of energy) is just right the electron moves to n = 2 or if it is just right it may move to n = 3 or n = 4 but nowhere in between. Quantized energy is energy in packets and atoms absorb energy in just the right size quantum. If the energy in the quantum is too large or too small to move the electron to a particular shell, the quantum just goes on and the atom is unaffected.
