What does a red shift tell astronomers about the movement of an object?
"Redshift", which means that the frequency of the light as seen by us is LESS than the frequency at which it was emitted, tells us that an object is moving away from us.
What front causes precipitation to fall for longer periods of time but less intensely?
Does a cold front cause precipitation to fall for longer periods of time but less intensely
If it is a cloudy day then how you will get solar energy?
Quite simply, you get less solar energy than when it is not cloudy. For example, a solar stove can still heat water, but it will no longer boil.Quite simply, you get less solar energy than when it is not cloudy.

How frequently does a tornado occur?
it's less frequent in the winter and fall and more grequent in the spring and summer in fact over 1000 tornadoes are confirmed every year and a thousand on average
What is the relationship between mass and the end stages of stars lives?
The more mass a star has the less time it has to live or "be a star." The less mass a star has the longer it has to live.
Why are short wavelengths of EM radiation less common then medium wavelengths?
Shorter wavelengths, like gamma rays and X-rays, require more energy to produce than longer wavelengths like visual light.
Why do the waves with shorter wavelengths scatter more than those with long wavelength?
Because they use less energy then longer wavelengths hence they can go farther
How does the energy assoicated with waves change wave length changes?
Longer wavelengths (and lower frequencies) have less energy. Shorter wavelengths (and higher frequencies) have more energy.
What happens to energy as a wave travels out from its source?
Energy is lost as it travels - thus the wave length grows longer. This is usually called 'redshift' as the wave radiated from the source shifts towards the less energetic red end of the electromagnetic spectrum (http://en.wikipedia.org/wiki/Electromagnetic_spectrum). Wikipedia has more information on redshift - http://en.wikipedia.org/wiki/Redshift.
Are shorter wavelengths more affected by a prism or water droplets than longer wavelengths?
False. A prism separates the colors of sunlight into a spectrum because each wavelength of light has its own index of refraction, not because wavelengths are affected more or less by the prism.
What is the longest wavelength?
There is no longest wavelength. In the electromagnetic spectrum extremely low frequency waves can have wavelengths of less than 100 megametres (100,000 kilometres or 10^8 metres). Gravitational waves are likely to have much longer wavelengths.
What color of the rainbow bends the most?
red. bending is a physical phenomenon called defraction , the less frequency ( or the longer the wave length) the more the defraction. since the red has the least frequency it bends more than any colour.
How is Infra-Red radiation detected at the focus of a telescope?
You need special optics to focus infra-red. The longer wavelengths do not focus at the same point (they are bent less by refraction). Mirror optics are better.
What processes produce the difference colors we see in opaque objects?
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.

The termrefraction means what in terms rainbows?
Water droplets refract different wavelengths of visible light differently. Blue wavelengths are less "bent" than red wavelengths, so the blue portion of the rainbow is towards the inside edge of the rainbow.
What wavelengths of electromagnetic radiation possess sufficient energy to be microbicidal?
Less than 300nm
