What Microwave reflection and detection means in Physics A-Level, as defined for OCR.
Definition of Microwave reflection and detection
Check what you remember
Read the wording for your board, then hide it and explain Microwave reflection and detection in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A transmitter directs waves at a metal plate; the reflected wave superposes with the incident wave, and a probe detects nodes and antinodes spaced λ/2 apart.
