Wave Basics and Types
This page introduces fundamental concepts of waves in GCSE Physics, focusing on transverse and longitudinal waves.
Waves are oscillations that transfer energy without transferring matter. They can be classified into two main types: transverse and longitudinal waves.
Definition: A wave is an oscillation that transfers energy without transferring any matter, by making the particles of the substance (or fields) that it is travelling through oscillate.
Transverse waves have oscillations perpendicular to the direction of energy transfer. Examples include light, electromagnetic waves, and water ripples.
Example: A transverse wave on a spring demonstrates oscillations perpendicular to the wave's direction of travel.
Longitudinal waves have oscillations parallel to the direction of energy transfer. Sound waves and compressions in a spring are examples of longitudinal waves.
The document introduces the wave speed equation for AQA Physics GCSE:
Highlight: Speed (m/s) = frequency (Hz) x wavelength (m)
This equation is crucial for solving waves GCSE Physics questions related to wave speed, frequency, and wavelength.
The page concludes by emphasizing that waves transfer energy but not matter, providing examples such as water ripples and sound waves to illustrate this concept.
