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.
Light is produced. Green light waves are absorbed into the grass. The human eye sees the image as green grass.
Which statement best describes the relationship between the frequency and the wavelength of waves?
As wavelength decreases, frequency remains the same.
As wavelength changes, there is no change in frequency.
As frequency increases, wavelength gets longer.
As frequency increases, wavelength gets shorter.
Which statement best describes visible light?
The human eye can only detect visible light as white light.
The frequency of visible light is the same as the frequency of gamma rays.
Visible light can only be seen with special equipment or technology.
Visible light makes up a small part of the electromagnetic spectrum.
