About the Physics

Beambox is inspired by the science of light, the characteristics of the different types of light (or electromagnetic radiation), and how contemporary society harnesses these characteristics to relay information in telecommunication technology and to realise many other applications.

Sunset gold, forest green, and sky blue – these are but a few of the magnificent colours we can see in nature, and visible light is only a sliver of the entire range of electromagnetic radiation that surrounds us! Scientists refer to the whole range of light, visible and invisible, as the “electromagnetic spectrum”.

The electromagnetic spectrum can be divided into different regions based on the way they are generated which relates to their wavelengths, frequencies and photon energies, as shown in the figure below (a more elaborate introduction can be found in “Learning Resources”). The different regions are known in everyday language as radio wave, microwave, infrared, visible, ultraviolet (UV), x-ray, and gamma rays. Each character in the Beambox installation represents a part of the electromagnetic spectrum; through play, the secrets of the electromagnetic spectrum unravel. We warmly invite you to come meet the Beamboxes and discover their talents!

If you take the time to explore the Beamboxes, you will discover that each face of a box contains a receiver or a transmitter that uses light to carry information. Each Beambox character has a distinct sound and colour, and the light it transmits carries information about these features. The information is “encoded” on the transmitted light by modulating the amplitude (or the brightness) of an LED at the transmitter. This process is called amplitude modulation (AM), a technique commonly used in radio alongside frequency modulation (FM). The modulated signal is then detected by the receiver of another Beambox that demodulates, i.e. decodes the signal. The receiver Beambox will then respond to the signal by changing its own colour and sound. Click here to peek inside Beambox to learn how it works and how to make one at home.

The way the Beamboxes communicate is also how information (phone, internet etc) is transmitted and received around the world. To learn more, please check out the Learning Resources. There are seven cubes, so there are many options for interactions. Come and play with them all to learn more about the electromagnetic spectrum.

Meet the Beamboxes

Beambox installation presents seven cubes that can communicate with each other. Each box represents an individual portion of the electromagnetic spectrum. Here is a quick introduction of our Beamboxes. Click on each picture to discover more about each Beambox story.



is the smooth sailor, considered and reliable, climbing every mountain.



is hungry to make the world a better place, one meal at a time.



is not who you want to keep your secrets.



is forever curious, forever seeking.



does not want to touch your germs.



is the shutterbug for science.



is the little bulldozer that could.
