Investigating the relationship between the image distance and the object distance for a convex lens
Fair testing
In this experiment I will be changing two factors which will be the object distance and the image distance.
The following factors that are going to be kept constant are:-
- The positioning of the image and light source – if this is changed; it could affect the results and may give anomoulous results. The light source must also point at the image and directly at the convex lens.
- The convex lens – if the size of this convex lens is change; it could again affect the results and may give anomoulous results.
- The light source – The intensity of the light source needs to be kept the same to prevent any anomoulous results.
- The bulb watt – this would have to be kept constant, i.e. if I use double the watt of the bulb than my overall outcome of results is will doubled.
