In physics class, I learned about the properties of convex mirrors.

This magic mirror came from China.

He attached a new reflector to his bicycle.

The speculum of this bird has a very beautiful color.

He was observing the stars with a telescope.

He conducted an experiment using a spherical lens.

This Tang mirror is a gift from China.

He is good at reading mirror writing.

His behavior is like a mirror image of his father.
