With clear explanations and practical examples, you'll have all the knowledge you need to tackle wave-related questions with confidence. Whether you're new to the topic or revising for your exams, ...

When waves meet a gap or an edge in a barrier, they continue through the gap or past the edge of the barrier. This may seem obvious but what happens on the far side of the gap or barrier is not so ...

Some questions in the exam will require you to recall and apply equations you have learned in class. Other questions will ask you to use the ‘Physics Equation Sheet’. This is a set list of equations ...

In this paper, we consider the numerical method for solving the two-dimensional fractional diffusion-wave equation with a time fractional derivative of order α (1 < α < 2). A difference scheme ...

Under investigation in this paper is a (2+1)-dimensional nonlinear Schrödinger equation (NLS), which is a generalisation of the NLS equation. By virtue of Wronskian determinants, an effective method ...
