👉 In mathematics, the term "imaginary number" refers to a complex number that cannot be expressed in the form of an exact real number. Imaginary numbers are often used in various branches of science and engineering, such as quantum mechanics, electrical engineering, and complex dynamics. In these contexts, they are used to describe quantities that do not exist in the real world but can be calculated using mathematical operations. For example, in quantum mechanics, imaginary numbers play a crucial role in describing wave functions for particles
