The objects that are used to refract light from the list provided are:
- your eyes: The lens in your eye refracts light to help you see.
- a telescope: Many telescopes use lenses to refract light in order to magnify distant objects.
- a camera: Cameras typically use lenses that refract light to focus images onto a sensor or film.
A brick, on the other hand, does not primarily function to refract light; it may cause scattering or reflection, but it is not designed for the purpose of light refraction.
So the correct answers are: your eyes, a telescope, a camera.
