Which is the correct sequence of events that allows human eyes to see

green grass?

• Light is produced. All light waves reflect off the grass. The human eye sees the image as green grass.

• Light is produced. Green light waves reflect off the grass.The human eye sees the image as green grass.

• Light is produced. All light waves are absorbed into the grass. The human eye sees the image as green grass.

What property of light allows humans to detect differences in color?

• the intensity of light the eye receives

• the wavelength of the light the eye receives

• the speed at which the light wave travels to the eye

• the distance the light wave travels from the source to the eye

What is the function of the eye’s retina and optic nerve?

• The optic nerve converts light to neural signals that are transmitted to the brain by the retina.

• The retina converts light to neural signals that are transmitted to the brain by the optic nerve.

• The retina focuses incoming light that is converted to neural signals by the optic nerve.

• The optic nerve focuses incoming light that is reflected by the retina.

When light passes through a prism, white light will be separated into different colors. Which statement best explains this observation?

• White light is reflected by the prism.

• Each color of light bends at the same angle.

• Each color of light bends at a different angle.

• White light is made of one wavelength of light.
