Hypothesis
I believe that as distance increases, the light
intensity will decrease as stated by the Inverse Square Law. The Inverse
Square Law states that as the intensity of light waves is inversely proportional
to the square of the distance of the wave to its source. For example,
if you measure 200mv at 1 m. and then move 2m. away, the measure should
be equal to
(1/22)X 200= 50mv.
I also believe that the energy saver light bulb
will produce the same amount of light intensity as the 60 watt light
bulb, since the manufacturers claim that they do. Also, I think that
the laser will have the most light intensity, considering that it is harmful
to shine a laser in your eye, but it is not as harmful to shine a normal
60 watt light bulb.
