Where might one find a natural light alarm clock?
A natural light alarm clock can be found in a few places. Some of these places include Full Spectrum Solutions, Sharper Images, Amazon, Walmart, Target, and Wayfair.
What r d differences between spectrometer and spectrograph?
A spectrometer measures the intensity of light as a function of its wavelength, providing a spectrum of the light. A spectrograph is an optical instrument that disperses light into its different wavelengths and records the resulting spectrum. In essence, a spectrometer is used to measure the spectrum while a spectrograph is the instrument that disperses and collects the spectrum.
Can rainbows be formed by prisms?
Yes, the refraction of light through a 60o prism will separate the light into a spectrum (a rainbow). Which then causes the light to refracted internally causing light to bend in different directions because of the speed of the light. Red light being the faster one and violet being the slowest one.
Where can you get light from?
Light can be obtained from various sources. One common source is the Sun, which produces natural light. Artificial light can be obtained from light bulbs, lamps, LED lights, or any other device that emits light.
How does red shift support the theory of the evolution of the universe?
The light spectrum can be viewed as a slinky. When compressed, the light waves change to the blue end of the spectrum. When stretched, the the light changes to the red end of the spectrum. Physicists know that our universe is expanding because galaxies further away change to the red end of the spectrum. This means the galaxies were once closer together in the past than what they are now. This is one of the many pieces of evidence that supports the Big Bang Theory.
