Thus parallels between the brightness of light and the loudness of sound, and between the colour of light and the pitch of sound, gave the clues for applying a wave theory to light when a wave theory of sound was already familiar.19 As Achinstein points out, physical similarities in some features of a pair of situations provide grounds for the plausibility of investigating possible similarities in other features.20 More typically, however, the substantive analogy is not observed but postulated, as when the physical properties of inertia and elasticity were attributed to the unobservable gas particles.

When the White light shines through the film of the bubble, the light is reflected and dispersed, splitting white light into its different wave length and showing all the colours!

This is because light from the sun contains a range of colours all with different wave lengths that when together form white light.

When the atom drops from the higher to the lower energy state, it emits a photon, or light particle, in the form of a radio wave 21 centimeters long.

In fact, just before posting this Top Pictures list, a NASA press release came out saying the Fermi satellite has seen gamma rays from this object, which is another very strong piece of evidence for this; gamma rays are the very highest energy form of light, and should be made when subatomic particles bounce around in supernova shock waves.

When the detector is locked and running, a change in the laser's light level, matched by a similar change at LIGO's twin in Hanford, could indicate a gravitational wave.

When the gravitational waters of spacetime are calm, the beams recombine at the junction and cancel each other out — the troughs of one beam's 1,064 - nanometer waves of laser light completely negate the crests of the second beam's waves.

This is the basis of linear optics: it is called «linear» because the division of electric charges that occurs when light passes through a medium is linearly dependent on the intensity of the fields in the light wave itself.

Instead of relying on light waves emitted by electrons, it would use radiation emitted when the nucleus is excited to a high energy state, and then drops into a lower energy state.

Now, when the laser beams rejoin, scientists see interference in the light's pattern, a jarring mismatch of peaks and valleys that spill the secrets of gravitational waves — if scientists can read through the static of local noise that can also jiggle the mirrors and mar the signal.

«When both atoms are in the non-coupling state the photon can enter the cavity, and a standing light wave between the two mirrors builds up,» says Bastian Hacker, another doctoral candidate on the experiment.

When a gravitational wave moves through the detector, though, it should stretch one arm of LIGO while shortening the other, changing the path of the beams and causing the rejoined waves to produce a detectable pattern of light.

Additionally, light that passes through a transparent object such as air, water or glass can also be refracted, which means the light wave bends when it passes from one transparent substance into another.
