A property of an object produced by the wavelength of light that the object reflects.

This lens turn to spread light out.

This type of lens concentrates light by bending the rays to a common point once they pass through.

Concave Lens

Convex Lens

TO SPREAD OR SCATTER. The separating out of different wavelengths of white light.

TO GIVE OFF SOMETHING as in the sun giving off light.

A tube through which can be seen symmetrical patterns caused by reflections from mirrors.

A FORM OF ENERGY. That energy emitted by the sun or by a chemical reaction to which the eye is sensitive.

Instrument that measures the intensity of light in a particular area.

TO GLOW OR TO GIVE OFF LIGHT at low temperatures. Like fireflies, lantern fish, glow sticks, glowworms

TO MAKE SMALL THINGS LOOK BIGGER by looking at them through one or more convex lenses.

A material that DOES NOT LET LIGHT PASS THROUGH.

A THREE-SIDED LENGTH OF GLASS. Light passing through it is refracted separating the colour of white light into a spectrum of colours.

As light passes through droplets of water a display of the spectrum of colours produced.

TO BOUNCE OFF OF A SURFACE. as in light bouncing off a mirror.

THE BENDING OF A LIGHT RAY as it pass from one medium to another.

A DARK IMAGE OR FIGURE CAST ON THE GROUND or some surface by an object blocking incoming light.

A MATERIAL THAT ALLOWS SOME LIGHT TO PASS THROUGH IT BUT SCATTERS THE LIGHT in the process so that images are not clear.

A MATERIAL THAT LETS LIGHT PASS THROUGH IT SO THAT OBJECTS CAN BE SEEN CLEARLY ON THE OTHER SIDE.

Opaque

Translucent

Transparent

A BAND OF COLOURS that makes up visible light. Each colour is generated by a different wavelength of light, the longest being red and the shortest being violet.

Light that contains all the wavelengths of colour in the visible spectrum from red to violet.
