GCSE Physics (9-1) - GCSE Physics - Longitudinal & Transverse Waves - Labelling & Calculating Wave Speed (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The function of waves * Waves transfer energy but do not transfer matter. 2. How to label the parts of a wave * Explanation of displacement-distance graphs. * Labelling amplitude, wavelength, crest, and trough. 3. Calculating wave frequency * Explanation of displacement-time graphs and time period. * Using the formula frequency = 1 / time period (f = 1/T). 4. Calculating wave speed * Using the wave speed equation: wave speed = frequency × wavelength (v = fλ). * A worked example for calculating wave speed. 5. Transverse and longitudinal waves * The difference between transverse and longitudinal waves. * Examples of both types of waves. *** CHAPTERS *** 0:00 Introduction to Waves 1:03 Labelling a Wave (Displacement-Distance Graph) 2:02 Labelling a Wave (Displacement-Time Graph) 2:28 Calculating Frequency from Time Period 3:42 The Wave Speed Equation 4:05 Wave Speed Calculation Example 4:42 Transverse vs Longitudinal Waves *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7VzYfPIVt8T09xOLNcolCe4&si=8JmDajxjtba6rdc3 https://youtube.com/playlist?list=PLidqqIGKox7UZ3mWhbHv2aA_1vnbsfRPq&si=q3hEKdA4v7kbfwMe https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
