Em spectrum

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also gain an understanding of the colors of the rainbow as the visible spectrum, each color corresponding to a different wavelength.

The CSIRO's Australia Telescope National Facility operates Australia's premier radiotelescopes.

You’re probably more familiar with the electromagnetic spectrum than you realize. In fact, you encounter it regularly every day.

How does a pyrotechnician, a scientist, translate chemicals into a fireworks art display for the viewer's enjoyment? To answer this question, we not only have to know how the elements and chemicals all around us can be manipulated to produce light and color, but we also need to know how the observer, us humble humans, SEE what we think of as "color."

Let us try to understand what is an electromagnetic spectrum and what is the importance of the EM spectrum in Astrophysics.
