When the light emitted by a distant galaxy is spectrographically analysed, it is found to contain the characteristic patterns of radiation emitted by famoliar elements, but their wavelength show a red shift of `2%`. How fast is the galaxy receding away from us? Using Hubble's law estimate the distance of galaxy in light year.
Take Hubble's constant `H=17kms^(-1)` for every million light year.

Text Solution

Verified by Experts

The correct Answer is:
`0.02c` or `6000kms^(-)`, 353 million light years

When the light coming form a galaxy in the constellation Ursa Major was spectro graphically anaylised, it was found to contain a line in the calcium absorption spectrum at a wavelenth of 4170Å , the wavelength of same line as observed on the earth is 3970Å . Is the galacy receidng away from us? What is the velocity of recession?

Consider a galaxy moving away from us with a speed of 6480kms^(-1) . It is a at a distance of 430 million light year from us, determine Hubble's constant H and corresponding age of universe t_(0)

Read the following text and answer the following questions on the basis of the same: Spectrum Analysis and Astronomy Each element in the periodic table can appear in gaseous form and produce its own spectrum unique to that element. Hydrogen will not look like Helium, which wil not look like carbon which will not look like iron....and soon. Astrophysists can identify what kinds of materials are present in stars from the analysis of star's spectra. This type of study is called astronomical spectroscopy. The science of spectroscopy is quite sophisticated. From spectrum lines analysis astrophysists can determine not only the element, but the temperature and density of that element in the star. The spectral line also can tell us about any magnetic field of the star. The width of the line can tell us how fast the material is moving. We can learn about winds in stars from this. The shifting of spectral liens shift back and forth indicates that the star may be orbiting another star. The following table shows a rough guide for the relationship between the temperature of a star and the electromagnetic spectrum. If the spectrum of a star is red or blue shifted, then it can be used to infer its velocity along the line of sight. Edwin Hubble observed that more distant galaxies tended to have more red shifted spectra. This establishes the theory of expansion of the universe. Which nature of spectrum establishes the theory of the expanding universe?

When a surface is irradiated with light of wavelength 4950Å , a photocurrent appears which vanishes if a retarding potential appears which vanishes if a retarding potential greater than 1.2 volt is applied across the phototube. When a different source of light is used, it is found that the critical retarding potential is changed to 2.1 volt. Find the work function of the emitting surface and the wavelength of second source. If the photoelectrons (after emission from the surface) are subjected to a magnetic field of 10 tesla, what changes will be observed in the above two retarding potentials. Use h=6.6xx10^(-34)Js , e=1.6xx10^(-19)C .
