Hint:The perfect way to answer this question is by understanding the superposition principle in mathematical terms. Schrodinger’s famous cat experiment will also be helpful to answer the question.
Complete answer:
The superposition principle, in mathematical terms, suggests that if two states are a solution to the equation then the linear combination of these two solutions is also a solution to the equation. For understanding this with an example, consider light emitted from a bulb. If the bulb is held so that it emits light in the north and east direction, the light should also emit in all directions from north to east.
Schrodinger’s cat is a wonderful example which is in terms of quantum superposition. This was a famous thought experiment or Erwin Schrodinger which had a radioactive source, a flask of poison, a cat and a device capable of detecting radioactivity and all are placed in a box.
When the device detects the radiation, the poison is freed and this results in the death of the cat. So, it can be seen that superimposition can be visualised as a state that simultaneously has multiple properties that conflict with each other,
Note:Apart from quantum mechanics, the superposition principle is also related to vector spaces. So, to give you a very layman, we can define any vector in the \[3-d\] plane from the $x$, $y$ and $z$-axis using the superposition principle in vector space.
