Most plants use light to create food through photosynthesis. Green pigments in an organelle called the chloroplast absorb the sun's light and use the light's energy to create simple sugars. A group of students decide that they want to run an experiment to see if they can use various types of light bulbs and still grow plants. They place plants in their closet to keep out all outside light. They also keep a lamp in the closet so that they can control the light that the plant gets exposed to. Every two weeks, the students check on the plant, record how it is doing. After all data is recorded, the students replace the plant with an identical one and change the color the light bulb. By the end of the experiment they have tried to grow plants under the following colors of light bulbs: red, blue, orange, green, black, and white. After the experiment, their data showed that only one plant didn't survive.

• The plant under the orange light.

• The plant under the blue light.

• The plant under the red light.

• The plant under the green light.

• The plant under the black light.

Which statement below is true?

• As the intensity of sound waves increase, the speed of the wave increases.

• As sound waves increase in intensity, the volume will also increase.

• As the intensity of a sound wave increases, so does the amplitude. However, has no effect on the volume.

• As the intensity of a sound wave increases, the frequency must also increase.

• Remus' and James' waves have the same amplitude, but Remus' has more energy than James'.

• James' wave has a higher amplitude and more energy than Remus'.

• Remus' wave and James' wave have the same amplitude and the same energy.
