Answer:

1.longitudinal

  • A wave motion in which the oscillations of the medium are parallel to the direction of propagation of the wave is called a longitudinal wave. Both transverse and longitudinal waves may be propagated within a continuous medium, provided that the medium has appropriate elastic properties.

2.period

  • The time for one complete cycle, a left swing and a right swing, is called the Period (T), can be found using only the length of the pendulum L, and the force of gravity g. T=2πgL. This proves that the mass of the pendulum did not affect its period.

3.wave length

  • The distance between successive crests (or successive troughs) is defined as the wave length. The time elapsed between the crossings of two successive crests through a given point is the period of the wave.

4.transvers

  • 4- Wave motion that is Perpendicular to wave direction describes a Transvers wave. 5- A Compressions or Rarefactions is the maximum displacement in a Longitudinal wave. 6- An Ocean wave would be an example of a Transverse wave.

5.frequency

  • Frequency is the number of waves that pass a given point in a certain amount of time.

6.electromagnetic

  • electromagnetic differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

7.highest surface

  • The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

8.hertz

  • The SI unit for frequency is the best heartz (Hz). One hertz is the same as one cycle per second.

9.rarefaction

  • Sound is an example of a longitudinal wave. A compression is where the particles of the medium are closest together, and a rarefaction is where the particles are farthest apart.

10.compression

  • In a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. Places where particles of a medium crowd closer together are called compression, and places where the particles spread farther apart are called rarefactions
