This is a slide show that shows images with the purpose of illustrating multiwavelength astronomy.

Part 1: Images of Centaurus A in different EM bands, including a key to where each EM band is on the spectrum. Concludes with a summary comparing the composite image to the visual and comparing the scale of Cen A on the sky to the full Moon.

Part 2: Images of Venus in different EM bands to show their different penetrating power. Includes a key to where each EM band is on the spectrum.

Part 3: Video analogy of musical octaves as EM bands and what "Ode to Joy" would sound like when restricted to a single octave. This is accompanied by images of the Sun in analogous bands.
