Paper 3 Section B

Manipulated variable (MV) : Object distance

Responding variable (RV) : Image distance

Constant variable (CV) : Type of lens

Inference: RV is depending on MV

Hypothesis : If MV increases / decreases then RV increases / decreases

Aim : To investigate the relationship between MV and RV

Variable : MV

RV

CV

List of apparatus ; copy from the question

Arrangement : simple diagram

Procedure : 4 or 5 steps

1. Arrange the apparatus as shown in the diagram
2. Explain how we going to start the experiment for 1 suggested value of manipulated variable, a
3. Explain how to obtain the responding variable
4. Calculation for the responding variable (if require)
5. Repeat the experiment with__b_, _c__, _d__, and __e__
