wave basics

• What do waves transfer from one place to another?

  Energy
• How do waves transfer energy?

  By oscillating particles in a medium
• What happens when you drop a twig into a calm pool of water?

  Ripples form without carrying the twig
• What do sound waves do when a guitar string is strummed?

  They transfer energy without moving air away
• What are the three key characteristics of waves?

  • Amplitude
  • Wavelength
  • Frequency
• What is the amplitude of a wave?

  Maximum displacement from undisturbed position
• How is wavelength defined?

  Distance between two adjacent wave points
• What does frequency measure?

  Complete waves passing a point per second
• How is frequency measured?

  In hertz (Hz)
• What is 1 Hz equivalent to?

  1 wave per second
• What is the period of a wave?

  Time for a full cycle to pass a point
• How can you find the period of a wave from its frequency?

  Using the formula $f =$$1/T$
• What is the only thing a wave transfers?

  Energy
• Why is it important to understand wave basics?

  • Foundation for understanding the topic
  • Essential for linking period and frequency
  • Helps in sketching wave diagrams
