Which of the following statements best describes how the human eye sees an object?

• Light must be refracted by the object and then absorbed by the eye.

• Light must be deflected by the object and then absorbed by the eye.

• Light must be diffracted by the object and then absorbed by the eye.

• Light must be reflected by the object and then absorbed by the eye.

• Object X is reflecting the yellow wavelength of light, and object Y is absorbing the yellow wavelength of light.

• Object X is diffracting the yellow wavelength of light, and object Y is reflecting the yellow wavelength of light.

• Object X is absorbing the yellow wavelength of light, and object Y is reflecting the yellow wavelength of light.

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.

• 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.

A student views a table of the speed of sound waves in three different materials. Material Speed (meters/second) air 330 water 1,500 glass 5,100 Which conclusion can be drawn based on the information in the table?

• Sound travels faster in glass because it has a lower density than the other materials.

• Sound travels faster in glass because it has a higher density than the other materials.

• Sound travels slower in water because it has a lower density than the other materials.

• Sound travels slower in air because it has a higher density than the other materials.

Which best describes the white light in the visible spectrum?

• a mixture of every wavelength and color of visible light

• a mixture of only seven colors and wavelengths of visible light

• a mixture of colors that cannot be broken up in the spectrum of visible light

A sound wave passes from air into water and then into steel. With each change in medium, what happens to the speed of the wave?

• It increases, then decreases.

• It increases.

• It decreases.

• It decreases, then increases.
