energy moves through it. Electromagnetic waves, such as light, behave like waves or ripples moving along a string. We can detect both of energy (sound and light) with our senses, and changing the properties of the wave corresponds with a change in perceptual experience. Larger waves are experienced as louder sounds or brighter lights; longer and shorter waves are experienced as notes of different pitches, or light of different colours; and single wavelengths are perceived differently to many wavelengths together. Finding the Science in Your Our ability to tell things by sight or sound depends on our senses’ abilities to tell the differences between large and small; long and short; and simple and complex waves. Themed Area—Seeing Colour The retina in an eye and a sensor array in a camera are both detectors that perceive colour. Different detectors have varying sensitivities to colour. This means that colour perception can vary greatly between individuals, species, and technologies. This area of the exhibition explores the functions and variation of some of these detectors. Galactic Colour Explore an interactive image of the night sky, and change between images of different spectral regions such as x-ray and radio waves. How to Use It Tap to select a spectral region; pinch and drag to zoom and pan; and turn labels on or off to show constellations and other astronomical objects. What Science Tells Us eyes are only sensitive to a small range of wavelengths of electromagnetic (EM) radiation (light). These correspond strongly with the most intense range of wavelengths present in the sunlight that falls to Earth. Certain scientific instruments are capable of capturing and measuring wavelengths that we cannot see. In the same way eyes use colour to learn about the properties of the world around us (ripe fruit vs unripe, time of day, fresh vs dry grass), this data can be used to understand the universe around us more deeply. Colour can be used to present data in a way that allows quick visual differentiation of regions. Several techniques for colouring data in this way exist, many of which are represented in the exhibit. Things to Try or Ask else is false colour used? Can you find features in one spectral region that are not visible in others? Compare one part of the night sky across several spectral regions. What changes do you observe? Finding the Science in Your World False colour is used in many places to represent data so it is easy to see. From rainfall radars to satellite imagery, thermal cameras, and population maps, colour coded data is all around us.
