Understand how to identify amplitude and frequency of waves and features of transverse and longitudinal waves with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

The slinky can be shaken to produce longitudinal and transverse waves. Examples of longitudinal waves include sound waves and earthquake p-waves. Examples of transverse waves include EM waves, water ...

The momentum and spin of a propagating photon are given by its wave vector and circular polarization, respectively. Bliokh et al.here show that evanescent electromagnetic waves possess a ...
