Edexcel GCSE Combined Science Topics P4 & P5 REVISION (Waves, Light & the EM spectrum)

This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content found within Topics P4 and P5 (Waves, Light and the Electromagnetic spectrum) of the Edexcel GCSE Combined Science specification.

The sub-topics and specification points that are tested within the lesson include:

• Define and use the terms frequency, wavelength, amplitude, period and wave velocity as applied to waves
• Describe the difference between longitudinal and transverse waves by referring to sound and EM waves
• Recall and use the two equations to calculate wave speed
• Describe how to measure the velocity of sound in air and ripples on water surfaces
• Explain how waves will be refracted at a boundary in terms of the change in direction and speed
• Recall that the EM waves are transverse and travel at the same speed in a vacuum
• Recall the main groupings of the EM spectrum
• Recall the potential danger associated with EM waves with increasing frequency
• Describe some uses of the EM waves

Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams
