Science waves

• The substance that a wave moves through is called medium
• wave lenght, period, amplitude, frequency, and wave speed are wave parts
• Mechanical waves require a medium to transfer energy away from their source.
• Sound waves are also mechanical waves that travel through the air, water, and solid matter.
• Electro magnetic waves are composed of oscillating magnetic and electric fields. It does not need a medium to transfer energy and it can travel in a vacuum.
• A sudden disturbance in which only one wave generated.

  wave pulse
• a series of disturbance

  wave train
• a movement of energy through space or a medium

  wave motion
• Longitudinal waves are those waves in which the particles of the medium move parallel to the propagation of the wave.
• Transverse waves are those waves in which the particles of the medium move perpendicular to the direction of the propagation of the wave.
• what are the two types of waves?

  Transverse and longitudinal.
• Compressions and Rarefaction
• Which of the following defines a wave?

  A . it is a vibration

  B . it is produced because of a disturbance

  C . it carries energy from one point to another

  D . all the choices above are correct

  D
• What waves are caused by the vibrations of earth?

  seismic waves
• To what type of wave is the voice being converted when you are using a telephone?

  sound waves
• Which of the following is a longitudinal wave?

  A . electrical waves

  B . electromagnetic waves

  C . pressure waves

  D . water waves

  c
• which of the following is not part of the electromagnetic spectrum?

  A . infrared

  B . sound waves

  C . x-ray

  D . visible light

  b
• True or False

  The light does not require a medium to travel.

  True
• What is the maximum displacement from the origin of the wave?

  amplitude
• what is referred to as the distance between two successive crests or troughs?

  wavelenght
• what happens to the frequency of a wave if the period decreases?

  increases
• which of the following waves do not need a medium to travel?

  A . electromagnetic waves

  B . mechanical waves

  C . wave pulse

  D . wave motion

  A
• which of the following are mechanical waves?

  A . seismic waves

  B . sound waves

  C . water waves

  D . all choices

  B
• which of the following is true about waves?

  A . matter moves with the waves

  B . waves are vibrations found in matter

  C . a disturbance is what causes waves

  D . as waves pass through matter, it causes oscillation

  C
• They do not carry energy as they travel. What is this?

  electromagnetic waves
• what happens to the frequency of a wave if the period increases?

  decreases
