We compare and contrast closed-ended, open-ended, and closed-on-one-end tubes. In this Closer Look segment on Standing Waves, we compare and contrast closed-ended, open-ended, and closed-on-one ...

In National 5 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.

Standing waves and their interactions with matter constitute the basis of modern physics, and they are involved in various fundamental phenomena over a wide range of scales. 1, 2 The De Broglie ...

We introduce mountain-pass type arguments in the context of orbital instability for Klein-Gordon equations. Our aim is to illustrate on two examples how these arguments can be useful to simplify ...
