What properties of gamma rays determine why it is found within the spectrum?
The only property that a ray or wave needs to have in order to be located within the electromagnetic spectrum is that it must be an electromagnetic wave. Gamma rays meet that requirement nicely.
What is the difference between a laser pointer and an infrared laser pointer?
An infrared pointer uses light that is mainly in the infrared spectrum, and so is mostly invisible to humans. A laser pointer in general refers to any device using a beam of light to mark an object. Both use the same basic technology. The only difference is the wave length. IR lasers are outside of the visual spectrum where as standard laser pointers are within the visual spectrum.
Is the colour of the ultra violet spectrum violet if not why was it given that name?
The ultraviolet spectrum is 'beyond' (ultra) the violet part of the visible spectrum, that is, beyond the short end of the wavelength range. The infrared spectrum is 'within' (infra) the long end of the wavelength range. The two terms have nothing to do with color, which defines the visible spectrum between violet and red.
Which em wave is only a small band within the broad electromagnetic spectrum?
A:visible light waves
Will red light passing through a prism eresult in a spectrum?
Yes and No, depending on the context of your question. The reason you get a spectrum with a prism is b/c of the principle of diffraction and superposition. The is based on optics and the angle of incidence and rarefraction of the OBJECT, NOT THE VISIBLE LIGHT SOURCE. With visible light, all of the possible wavelength in the visible specrtum are contained within this wave pattern (called superposition). When visible light reflects off objects and sends signals (diffraction grating) to your eyes, your retinas, and later your brain, perceive these particular patterns of light rays and generate images. Because red light is part of the visible spectrum, and because you can alter the properties of the incident object, any color of light in the visible spectrum could appear.

How was infrared discovered?
According to NASA infrared radiation was first discovered in 1800, by a British astronomer named William Herschel. In an experiment to measure the difference in temperature between the colors in the visible spectrum, he placed thermometers in the path of light within each color of the visible spectrum. He observed an increase in temperature from blue to red, including an even warmer temperature measurement just beyond the red end of the visible spectrum.

Physical properties within a period are more alike than physical properties within a group true or false?
False. Properties within a group are more alike than properties within a period.
Why are peaks important in spectroscopy?
In the field of spectroscopy absorption a peak means the wavelength of radiation where a sample absorbs. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands, each one corresponding to structural groups within the molecule. Each band is represented by peak if you plot absorbance vs wavelength. By knowing which structural groups correspond to which peaks, you can often identify a compound by it's spectrum. For many molecules, the spectrum has been characterized, and you can use the spectrum to determine the purity, concentration, or other properties of the molecule by looking at the position and intensity of the peaks in the absorption spectrum.
Are properties within a group are more alike than properties within a period?
true
Properties within a group are more alike than properties within a period.?
true
How does the light that astronomers see from distant stars and galaxies tell htem that the same atoms with the same properties exist throughout the universe?
We determine the types of elements contained in the star or within the corona by analyzing the spectrum of the light we receive. Each element will radiate at a set of specific discreet frequencies, and the frequencies they radiate tell us what the element is, and how deeply ionized it is. The spectral analysis is exact; we can even determine the proportions of the elements that we see by the relative brilliance of their light. But there IS one thing that the spectrum cannot tell us; is this a normal matter star, or an anti-matter star?
What is thermal infrared imagery?
Electromagnetic radiation in the range 5.6micrometre to 1.0 cm is called thermal infrared range.Green house gases absorb and emit radiation within this range.Green house gases in the earth's atmosphere are water vapour,carbon dioxide,methane,nitrous oxide and ozone
What is the relationship between electromagnetic spectrum and sight?
Different wavelengths on the spectrum are seen as different colors within the visible light section of the spectrum.
