    Position of a point in space, not necessarily a point on the wave profile or any line of propagation d, r: m [L] Wave profile displacement Along propagation direction, distance travelled (path length) by one wave from the source point r 0 to any point in space d (for longitudinal or transverse waves) L, d, r

  3. Beaufort scale - Wikipedia

    en.wikipedia.org/wiki/Beaufort_scale

    Sir Francis Beaufort. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded ...

  4. Wind wave - Wikipedia

    en.wikipedia.org/wiki/Wind_wave

    A man standing next to large ocean waves at Porto Covo, Portugal Video of large waves from Hurricane Marie along the coast of Newport Beach, California. In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface.

    en.wikipedia.org/wiki/Heinrich_Hertz

    Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.

  6. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Transverse waves that exhibit polarization include electromagnetic waves such as light and radio waves, gravitational waves, [6] and transverse sound waves (shear waves) in solids. An electromagnetic wave such as light consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other.

  7. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line).

  8. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    A standing wave, also known as a stationary wave, is a wave whose envelope remains in a constant position. This phenomenon arises as a result of interference between two waves traveling in opposite directions. The sum of two counter-propagating waves (of equal amplitude and frequency) creates a standing wave. Standing waves commonly arise when ...

  9. Douglas sea scale - Wikipedia

    en.wikipedia.org/wiki/Douglas_sea_scale

    The Douglas sea scale is a scale which measures the height of the waves and also measures the swell of the sea. The scale is very simple to follow and is expressed in one of 10 degrees. The scale is very simple to follow and is expressed in one of 10 degrees.
