Wave Amplitude and Intensity - A Level Physics

In this video I explain two more properties of waves: amplitude and intensity, for A Level Physics. This catches lots of people out. If you double the amplitude of a wave you give it four times as much energy, this leads on to the relationship between amplitude and intensity of a wave. Thanks for watching, Lewis This video is recommended for anyone studying A Level Physics in the following exam boards: AQA CIE Edexcel Edexcel IAL Eduqas IB OCR A OCR B WJEC _____________________________________ MY PHYSICS WEBSITES Find even more videos organised by exam board and topic at: GCSE Physics Online ► https://www.gcsephysicsonline.com A Level Physics Online ► https://www.alevelphysicsonline.com MY YOUTUBE CHANNEL Your support in watching this video has been invaluable!
