Question

scientists use near-infrared waves, a type of infrared wave with wavelengths close to those of visible light, to monitor the health of earths plants. typically, healthy plants reflect more near-infrared waves than unhealthy plants. the opposite is true for visible light. healthy plants reflect less visible light than unhealthy plants.this model shows the percentage of visible light and near-infrared waves reflected by two different plants.50% near-infrared waves8% visible light40% near-infrared waves30% visible lighthealthy plantunhealthy plantcomplete the sentences.the healthy plant reflects about ▼ of near-infrared waves and about ▼ of visible light. the healthy plant reflects ▼ near-infrared waves than the unhealthy plant reflects.

Explanation:

1. Extract the reflection percentages directly from the diagram for the healthy plant.
2. Compare the near-infrared reflection values of the healthy and unhealthy plant to determine the relationship.

Answer:

The healthy plant reflects about 50% of near-infrared waves and about 8% of visible light. The healthy plant reflects more near-infrared waves than the unhealthy plant reflects.
