This “Properties of Waves” PowerPoint lesson is designed for AQA GCSE Physics students, covering key wave characteristics such as frequency, wavelength, amplitude, and wave speed. It introduces essential equations, including wave speed = frequency × wavelength, and develops students’ ability to calculate and analyze wave behavior through real-world applications and practice questions.
The lesson starts with a starter activity revisiting key concepts from Lesson 1: Introduction to Waves, ensuring students understand transverse vs. longitudinal waves, amplitude, and wavelength. Students then move on to defining frequency, understanding how it is measured in hertz (Hz) and calculated using the formula: frequency = number of waves / time taken.
The lesson features a demonstration using a ripple tank, where students observe wave behavior and define wavefront. They explore how the number of waves per second (frequency) relates to the time for one complete wave (period) and complete calculations using: period = 1 / frequency
Students then apply the wave speed equation: Wave speed = Frequency × Wavelength. They work through step-by-step calculations, rearrange the equation to solve for different variables, and answer GCSE-style questions. The lesson also introduces standard form calculations, preparing students for more advanced physics applications.
Updated in February 2025, this editable PowerPoint (.pptx) file is fully aligned with the AQA GCSE Physics specification and includes structured explanations, worked examples, and interactive activities, making it a valuable resource for teaching wave properties, calculations, and practical applications in GCSE Physics.
