In an experiment the hypothesis is if the wavelength of the light shining on a plant is shortened the rae of the photosynthesis
is slowed down, if the experiment is preformed the independent variable .. A) will be the wavelength of the light
B) will be the plant on whcih the light is shining
C) will be the rate of photosynthesis
D) can not be determined
The independent variable in any experiment is what YOU change and then you look to see the result of the change.
In this experiment, the independent variable is the wavelength of the light. (A) Nothing happens until the person doing the experiment changes the wavelength of the light. When he DOES that, he looks to see whether it affected the health and behavior of the plants.
