Bench ruler - Study guides, Class notes & Summaries

for 1 allow ‘reads / measures height of detector’ / ‘distance from detector to bench’; reject ‘measures height of clamp T’ if ‘subtracts 138’ is not seen; allow ‘subtract distance from source to bench’ / ‘between source and bench’ / ‘height of source from ground’ / ‘position of top / open end / mouth of source’; allow ‘measures height of the detector and the source and finds difference’; condone ‘reversed’ subtraction, for 2 expec...

Physics - Mark scheme instructions to examiners 1. General The mark scheme for each question shows:  the marks available for each part of the question  the total marks available for the question  the typical answer or answers which are expected  extra information to help the Examiner make his or her judgement and help to delineate what is acceptable or not worthy of credit or, in discursive answers, to give an overview of the area in which a mark or marks may be awarded. The e...

A student investigates stationary waves using microwaves. Figure 1 shows a metre ruler fixed to a bench. The student places a microwave transmitter T at one end of the ruler and a vertical metal reflector R at the other end. R is at a right angle to the ruler. Figure 1 The student places a microwave detector D approximately one-third of the distance from T to R. When T is switched off, the microammeter connected to D reads zero. When T is switched on, stationary waves are produced betwe...
