Are Electromagnetic Waves Always Transverse? Full Explanation

June 23, 2020/5 Comments/in Electromagnetism, Physics Articles/by Delta2

Electromagnetic (EM) waves are always transverse in the weak sense: the electric field (E) and magnetic field (B) are always perpendicular to the direction of energy flow, given by the Poynting vector. They are not always transverse in the strong sense, which additionally requires E and B to be perpendicular to each other. That stronger…

Fundamental Theorem of Calculus: An Intuitive Numerical View

November 8, 2018/9 Comments/in Analysis, Physics Articles/by Delta2

The fundamental theorem of calculus states that integration and differentiation are reverse operations of one another. This article gives an intuitive, non-rigorous numerical explanation of why this is true, using discrete sums and finite differences rather than limits, so readers can build intuition before tackling the formal analytical proof. Key Takeaways The explanation relies on…
