In an experiment, the hypothesis is if the wavelength of the light shining on a plant is shortened, the rate of the photosynthesis is slowed down. this hypothesis testable falsifiable both of the above none of the above

Both of the above

Explanation:

Falsifiable means that some observation might show it to be false. In this case, I can perform a test in which the wavelength of the light shining on a plant is shortened, and the rate of the photosynthesis is not slowed down; then, the hypothesis is falsifiable.

A testable hypothesis is a hypothesis that can be proved or disproved as a result of testing. Again, I can perform a test in which the wavelength of the light shining on a plant is shortened, and measure the rate of the photosynthesis; then, the hypothesis is testable.
