Definition 2
Focal length the distance amid the optical centre to the focal point.
Lens type
Risk assessment
askew floor this is a risk as people tin fall over, this rouse cause damage to equipment and people. This risk washbowl be minimized by paying attention to youre surroundings.
Other people desire a wet floor, this can be a danger if you hit someone, this can be prevented though if you run across into someone and drop equipment and/or molest yourself.
Glass breakage - this can cause damage as glass shards can break and make a sphere of influence dangerous, the glass can break into skin and cause damage
Tables - like a wet floor, a table can be dangerous If you are not mindful of its position and you bump into it.

Hypothesis
My hypothesis is that the width of a lens bequeathing affect its focal point, I plan to test this by using diametrical width lens of the same natural and testing them, measuring the focal point in millimetres and therefore checking if there is a difference.
PLAN the p[an for my experiment is to get 5-6 different types of lens and measure the focal length of each one. This will be how I conduct the experiment and it will be measured in millimetres.
Prediction I predict that the capillary the lens, the further off the focal point will be for each lens, the experiment I will repeat 3 times for each lens, and the find out the average, so it is all accurate..
My results table for the work
My results are showing me that the thinner focal lenses have a much large focal length than the thicker lenses.
