Newton also developed the reflecting telescope.

Despite the theoretical advantages of the reflector design, the difficulty of construction and the poor performance of the speculum metal mirrors being used at the time meant it took over 100 years for them to become popular.

In astronomy, reflection nebulae are clouds of interstellar dust which reflect the light of a nearby star or stars.

The parabolic reflector transforms an incoming plane wave traveling along the axis into a spherical wave converging toward the focus.

And then you go a little crazy, and so you do various optical components or you do microprism arrays, like the reflective tape that you have on your running shoes.

The Swarovski Group also includes Tyrolit (makers of abrasive and cutting tools) Swareflex (reflective and luminous road markings) Signity (synthetic and natural gemstones) and Swarovski Optik (optical instruments such as binoculars and rifle scopes).

In Oxford, perhaps we can use Lewis Carroll and look in the looking glass that is New York City to try and see our true selves, or perhaps pass through to another world.

So if I put this inside this water here, you can see a silver reflective coating around it, and that silver reflective coating is the layer of air that's protecting the water from touching the paddle, and it's dry.

So, much like you're seen at night by a car, then the idea is that you can see, if you illuminate tissue, you can see deeper parts of tissue because there is that reflective tape there that is made out of silk.

The transparent façade is a unique design feature, because most buildings have only a single façade using highly reflective glass to lower heat absorption, but the Shanghai Tower's double layer of glass eliminates the need for either layer to be opaqued.
