Is knowledge of numerical methods and knowledge of complex numbers required for the Physics Aptitude Test for Oxford University?
And what about complex numbers? Are they used often in physics?
Yes, complex numbers are used extensively in physics, particularly in the study of electromagnetism and quantum mechanics. They are used to represent quantities such as electrical impedance and wave functions, which can have complex values. Understanding complex numbers is essential for understanding these areas of physics.
