Complete “Ready to go” lesson with no adapting necessary!
New for AAQ Pearson Applied Science BTEC from Sept 2025 Specification
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
This lesson covers:
•Recall of EM waves and a student task that allows students to revisit content from the previous lessons and apply knowledge to identify the properties that EM waves share in common
•Properties and uses of EM waves recap/content
•Explanation of the inverse square law by introducing what intensity is and how it is determined by power and area, this builds up to explaining the inverse square law in terms of I ∝ 1/r^2. This is then further built to explain how we can change this into I = k/r^2 to calculate intensity and where that formula is derived from.
•Students practice questions on the inverse square law that use application and calculations with substitution and rearranging
•Practical investigating inverse square light by increasing distance and measuring light intensity with follow up questions and sample data if required

NO PRINTING REQUIREMENTS
