Transverse and Longitudinal

• What do waves transfer from one place to another?

  Energy
• How do waves transfer energy?

  Without transferring any matter
• In which direction do waves travel?

  In the direction they are traveling
• What happens to particles in a medium when waves travel through it?

  Particles oscillate and transfer energy
• What do ripples in water demonstrate about wave energy transfer?

  They show energy transfer without water movement
• What do sound waves do when created by a guitar string?

  They create sound waves without moving air away
• What is the amplitude of a wave?

  Maximum displacement from its undisturbed position
• What is the wavelength of a wave?

  Distance between two adjacent wave peaks
• How is frequency defined in wave terms?

  Number of complete waves passing a point per second
• What unit is frequency measured in?

  Hertz (Hz)
• What does 1 Hz represent?

  One wave per second
• How can you find the period of a wave from its frequency?

  Period = 1 / frequency
• What are the two types of waves based on direction?

  Transverse and longitudinal waves
• What are the characteristics of transverse waves?

  • Particles move perpendicular to wave direction
  • Examples: light waves, water waves
• What are the characteristics of longitudinal waves?

  • Particles move parallel to wave direction
  • Examples: sound waves
• What do transverse waves create in a medium?

  Sideways vibrations
• What do longitudinal waves create in a medium?

  Compression and rarefaction
• How do sound waves differ from light waves?

  Sound waves require a medium, light waves do not
• How do waves interact with each other?

  They can interfere constructively or destructively
• What is the significance of wave interference?

  It affects the amplitude and energy of waves
• What is a wave's crest?

  The highest point of a wave
• What is a wave's trough?

  The lowest point of a wave
• What does the term "wave speed" refer to?

  The speed at which a wave travels through a medium
• How is wave speed calculated?

  Wave speed = frequency × wavelength
• What is the relationship between frequency and wavelength?

  Inversely proportional in a constant medium
• What happens to wavelength if frequency increases?

  Wavelength decreases
• How do sound waves differ in different mediums?

  They travel faster in solids than in gases
• What is the Doppler effect?

  Change in frequency due to relative motion
• What is the effect of the Doppler effect on sound waves?

  Higher frequency when approaching, lower when receding
• How does the medium affect wave properties?

  It influences speed, frequency, and wavelength
• What is the significance of wave reflection?

  It allows waves to change direction and energy transfer
• What happens during wave refraction?

  Waves change direction when entering a different medium
• What is wave diffraction?

  Bending of waves around obstacles
• How does wave interference create patterns?

  Constructive and destructive interference leads to patterns
• What is the relationship between wave energy and amplitude?

  Higher amplitude means greater energy
• How do waves carry information?

  By modulating amplitude, frequency, or phase
• What is the role of a medium in wave propagation?

  It facilitates the transfer of energy
• What is the significance of wave properties in technology?

  They are essential for communication and energy transfer
• How do waves interact with the environment?

  They can be absorbed, reflected, or transmitted
• What is the importance of studying waves in science?

  It helps understand energy transfer and communication
