When sunlight hits water, not all of it penetrates the surface, and the deeper you go the larger percentage of light that has been deflected, reflected, or absorbed. The exact percentage of light that reaches a certain depth depends on several factors. In one lake, a researcher discovered that any change of 10 meters in depth reduces the amount of light reaching that depth by 22.8%. a. What is the 10-meter percent change in the amount of light available under water in this lake? Select an answer Preview b. What is the 10-meter decay factor in the amount of light available under water in this lake? Preview
