A student creates a transverse wave using a rope tied to a tree. Her teacher asks her to change the wave to show a greater energy transfer. What can the student do?

• She can increase the frequency of the wave.

• She can decrease the amplitude of the wave.

• She can decrease the frequency of the wave.

• She can increase the wavelength of the wave.

Read the passage about color blindness. Color blindness is the decreased ability to see colors. Red-green color blindness is the most common form. Individuals who are color blind have a difficult time seeing different wavelengths of light. Now there is new technology, in the form of glasses, that will allow a red-green color-blind person to see these colors. Which statement best explains how the glasses will help a color-blind person see color?

• The glasses physically fix the individual's eyes so they can see the different wavelengths of light and the different colors.

• The glasses change the way the wavelengths of light are filtered by the individual's eyes so they can see colors.

• The glasses add the different wavelengths back into the light so the individual can see the different colors.

• The glasses filter out all other wavelengths of light so the individual only sees the colors they could not see before.

Carla's favorite ball is bright blue when it is outside in the direct sunlight. Inside, the ball appears to be almost green. Why does Carla's ball seem to change colors?

• Color is determined by the density of an object, and Carla's ball became more dense when she went inside out of the sunlight.

• Color is determined by the size of an object, and Carla's ball lost air while being played with, so it was smaller when she went inside.

• Color is determined by the wavelength of light reflected or absorbed by the object, and the light changed when Carla went inside.

• Color is determined by the temperature of an object, and the temperature changed when Carla went inside out of the sunlight.
