Notice the tuning fork is vibrating and sending sound waves through the air. Analyze the type of wave and describe the motion of the particles.

• A) This is a transverse wave because the particles move perpendicular to the direction of travel.

• B) This is a transverse wave because the particles move parallel to the direction of travel.

• C) This is a longitudinal wave because the particles move perpendicular to the direction of travel.

• D) This is a longitudinal wave because the particles move parallel to the direction of travel.

Which of the waves in the following diagrams can be used to represent a high volume?

• Wave 2 can be used to represent high volume because it has high energy

• Wave 2 can be used to represent high volume because it has a higher amplitude

• Wave 1 can be used to represent a high volume, because it has high energy.

• Wave 3 can be used to represent high volume because it has low energy

Which statement below can be used to explain the student's observations about the ultraviolet ray model?

• A) Waves cannot change speed

• B) The ultraviolet ray increases its wavelength as it passes through the second material.

Which of the following statements can be used to explain why leaves appear green during the summer and red during the fall?

• During the summer the chloroplasts reflect green light and absorb the other colors of the visible spectrum. During the fall, the chloroplast are stored in the branches to prepare for winter. The leaves begin to reflect red and orange light and absorb the other colors of the visible spectrum.

• During the summer the chloroplasts absorb green light and reflect the other colors of the visible spectrum. During the fall, the chloroplast are stored in the branches to prepare for winter. The leaves begin to absorb red and orange light and reflect the other colors of the visible spectrum.

• During the summer the chloroplasts absorb all of the colors of the visible spectrum.

• During the summer the chloroplasts reflect all of the colors from the visible spectrum. Green has the highest energy, making it more visible. During the fall, the chloroplast are stored in the branches to prepare for winter. The leaves begin to reflect red and orange light, because their energy increases as it gets colder outside.
