What are Waves? Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What are waves?

Waves are oscillations or vibrations that transfer energy without transferring matter.

What is the difference between longitudinal and transverse waves?

In longitudinal waves, oscillations are parallel to the direction of wave travel, while in transverse waves, oscillations are perpendicular to the direction of wave travel.

Give two examples of longitudinal waves.

Sound waves and ultrasound waves.

Give two examples of transverse waves.

Visible light and water waves.

What are the features of a wave?

Peak (highest point above the midpoint), trough (lowest point below the midpoint), wavelength (distance between two identical points), and amplitude (distance from midpoint to peak or trough).

What is frequency and how is it measured?

Frequency is the number of complete waves that pass a given point per second, measured in Hertz (Hz).
