What would be observed if the flame tests were viewed through a spectroscope?
Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc
What is infra red spectra stretching?
In molecules, there are bonds. When they are exposed to infra-red radiation, different bonds absorb the infra-red radiation at different wavelengths. In the observed spectrum, there are "bond stretches", where the observed intensity of certain wavelengths drops due to the absorption. By comparing these "stretches" with a data-booklet, you can see which bonds the molecules have. This is called Infra-red Spectroscopy.
What are the features of a gamma ray?
Gamma rays are electromagnetic waves ... physically and functionally identical to radio, light, heat, etc. ... with the highest observed frequencies (shortest observed wavelengths). In experiments designed to reveal the particle nature of electromagnetic radiation, gamma ray particles (photons) have the highest observed photon energies.
Is diffraction the tightening of waves?
No.Diffraction is the change in the direction and intensity of a group of waves after passing an obstacle or passing through an aperture whose size is comparable to the wavelength of the waves.It can be observed in mechanical waves, electromagnetic waves as well as in matter waves.When a beam of light falls on the edge of an object, it bends slightly due to the contact and causes a blur at the edge of the shadow of the object. Waves of longer wavelengths are diffracted more than those of shorter wavelengths.
What forms of energy can be observed?
Visible light is electromagnetic radiation. Use the link below to read more. There's a whole world of knowledge in the nature and behavior of light, but it is something that can be understood. After all, it's not rocket science.
Why is there a line spectrum over a continuous spectrum in a spectroscope?
The lines in a spectroscope tell what element(s) are being observed. The continuous color are background noise or put there for a reference.
What causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.

Based on the observed red shifts in the spectral lines of distant galaxies?
Astronomers conclude that the universe is expanding, because wavelengths are increasing.
Describe the common characteristics of flame tests that would be observed if a spectroscope were used?
Not a god danm thing it's utterly pointless don't even bother chemistry isn't even important.

Two planets that radiate away more energy than they receive from the sun are?
It depends a bit on what radiation wavelengths are observed. The basic answer is Jupiter and Saturn.
What is the difference between the red shift and the blue shift?
A "redshift" is a change in the light observed from a source to longer wavelengths. That's a change from the blue end of the spectrum to the red end of the spectrum. A "blueshift" is the opposite. It's a change towards shorter wavelengths.
Why are carotenoids coloured?
Carotenoids have conjugated bonds. Wavelengths of visible light are absorbed when electrons are excited to higher energy levels. The complementary colour is to that absorbed is observed.

In experiments designed to reveal the particle nature of electromagnetic radiation, gamma ray particles (photons) have the highest observed photon energies.
Which of the following types of eclipses will NEVER be observed?
Annular lunar eclipse
Where in the electromagnetic spectrum are pulsars best observed?
Pulsars are best observed in the radio part of the electromagnetic spectrum. This is because their strong radio emission allows them to be detected and studied using radio telescopes. However, pulsars have also been observed at other frequencies, including X-ray and gamma-ray wavelengths.
