Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.

• The wavelengths get shorter but there is no change in amplitude.

• The wavelengths get longer and there is an increase in amplitude.

• The wavelengths get longer and there is an decrease in amplitude.

• The wavelengths get shorter and there is an increase in amplitude.

Which is the best description of the light paths necessary to see an object?

• Light must travel one path from the source to the eye, and another path from the eye to the object.

• Light must travel one path from the object to the source, and another path from the source to the eye.

• Light must travel one path from the eye to the source, and another path from the source to the object.

• Light must travel one path from the source to the object, and another path from the object to the eye.

You are able to see an object if it either makes its own light (a light source), or it reflects light to your eyes. This information makes which of these statements true?

• Seeing outside is difficult on a night with no moonlight.

• The eye reflects light to a light source to create images.

• Light travels from objects to light sources, and then to your eyes.

• Objects can become their own light sources if they absorb enough light.
