What object allows some light to travel through it in straight lines? (2 points)
O Book
O Door
Sunglasses
O Mirror

Explanation:

Books, doors (not glass doors), and mirrors are supposed to reflect the light. They are opaque. They do not transmit light. Then, they do not allow some light to travel through them. Then, discard them.

The materials that transmit light, i.e. which allows light to travel through them are either translucent of transparent.

The transparent objects allow most of the light travel through them in straight line: clear glass are transparent, because most of the light passes straight through them.

The translucent objects do not permit to look clearly through them because the light changes direction multiple times distorting the image too much: some plastics are translucent.

Sunglasses fliter (stops) the UV ligth, but most of the visible light travels through them in straight lines. Thus, this is the correct choice.
