| We report the Fresnel reflection coefficients modified due to excitation of the longitudinal waves in metals. |
| They are thus described as longitudinal waves, defined by their frequency and amplitude. |
| On the other hand, sound waves, for example, are longitudinal waves and cannot be polarized. |
| The longitudinal waves are deeper and faster than the transverse waves which follow as aftershocks. |
| In physics, there are standing waves, longitudinal waves and transverse waves, to name just a few. |
| They are classified in the categories transversal and longitudinal waves, and so all known phenomenae can be explained. |
