This Pearson BTEC Applied Science Unit 1 Physics PowerPoint covers wave speed and the wave equation, including calculations, unit conversions and standard form.

Designed for the Waves in Communication topic, this comprehensive lesson develops students’ understanding of how wave speed is calculated and its relationship with frequency and wavelength. Wave speed is defined as the distance travelled by a wave per second, describing how quickly energy propagates from one location to another.

The PowerPoint includes a starter activity, clearly defined learning objectives, key scientific terminology, detailed explanations and worked examples with answers. Students learn to calculate wave speed using distance and time before progressing to the wave equation (v = fλ). They practise rearranging the equation to calculate wave speed, frequency and wavelength, developing essential mathematical skills required for BTEC Applied Science assessments.

The lesson also covers SI units, unit conversions and standard form, including converting between millimetres, centimetres and metres, and between kilohertz, megahertz and hertz. Students explore the inverse relationship between frequency and wavelength when wave speed remains constant.

Throughout the lesson, students apply their understanding through structured calculations, practice activities and examination-style questions. The resource concludes with 12 Check Your Understanding questions with answers, alongside past paper questions and further calculation practice, providing opportunities for assessment, consolidation and exam preparation.

This resource is suitable for classroom teaching, independent learning and revision for students studying Pearson BTEC Applied Science Unit 1 Physics.
