Investigating light.

What is the fastest way to travel through the universe.

What is light speed.

Define optical science.

What is fibre optics.

Name three objects that help us see very small objects or objects far away.

1: Search Result launched  by NASA in 2006, it shot directly to a solar system escape velocity. This consisted of an Earth-relative launch of 16.26 kilometres a second (that's about 36,000 miles per hour), plus a velocity component from Earth's orbital motion (which is 30 km/s tangential to the orbital path)

2: 299 792 458 m / s

3: Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

4: An optical fibre is a flexible, transparent fibre made by drawing glass or plastic to a diameter slightly thicker than that of a human hair.

5: Telescope,microscope,magnify glass.
