Question 1.<\/h4>\n<\/td>\n<\/tr>\n

<\/td>\nWhen you look at a light from different distances you will see that the brightness of the light depends on how far you are from it.\u00a0 Two students set out to investigate this in more detail.<\/p>\n

They set up the apparatus as shown:<\/td>\n<\/tr>\n

<\/td>\n\u00a0\"\"<\/td>\n<\/tr>\n
<\/td>\n\u00a0They record the following results:<\/td>\n<\/tr>\n

<\/td>\n\u00a0What conclusion could the students draw from the results of their experiment?<\/td>\n<\/tr>\n
