Science Centre, KidsSTOP™ and Omni-Theatre are closed on 25 June 2018.

The Crane exhibit in KidsSTOP™'s Built Environment is under maintenance. Sorry for the inconvenience!

Please note that the Science Centre exhibitions will be closed on all Mondays except school and public holidays. Lab lessons for schools will continue as per normal on closure days. We thank you for your understanding.

 

Spectroscopy is a class of techniques that investigates how radiation (such as, but not limited to light) is affected by interactions with matter. Our understanding of the world is largely based on spectroscopy for example, many chemical elements were first discovered through their spectra, and our knowledge how atoms and molecules are built has been almost entirely derived from spectroscopic observations. In this non-mathematical workshop, Participants build their own spectroscopes (which they can keep and use for further investigations) and use them to observe spectra of various light sources, culminating in the observation of Fraunhofer spectral lines in daylight. The characteristic properties of different types of spectra (atomic, molecular and solid-state origin) are qualitatively explained.

light; thin lens; real & virtual images; electromagnetic spectrum, waves; superposition (diffraction); energy levels; line spectra; atomic structure; covalent bonding; chemical elements/periodic table, orbitals; chemical bonding
