Question

The Sun Sunspot Jet passing in front of the Sun Warning: Never look at the Sun without the proper equipment. Introduction Below is diagram showing the layers of the Sun that can be directly observed. We can only "see" into the interior with sophisticated techniques such as helioseismology. Corona Chromosphere Photosphere Interior of the Sun Region of the Thickness (km) Density T Temperature (K) (kg/m3) Sun 150,000 at core 15 million at core 696,000 Core to Photosphere 5800 2 x 10-4 Photosphere 500 4500 5 x 10-6 1500 Chromosphere 1 million about 1 million 10 12 Corona (turns into the Solar Wind)

Explanation / Answer

1.1 H beta has greater energy than H alpha since we know that wavelength and energy has inverse relation. Higher the wavelengh, lesser will be the energy. The wavelength of H alpha is 656.28nm whereas that of H beta is 486.13nm. So the wavelength of H beta is shorter than H beta which means that the energy of H beta will be more than H alpha.

3.2 To calculate the frequency of H alpha photon we use following formula

Wavelength* frequency=3*108m/s

Given wavelength=656.28nm

Since 1nm=10-9m

Wavelength in m=656.28*10-9m

frequency=??

Now 656.28*10-9m* frequency=3*108m/s

frequency=3*108ms-1/656.28*10-9m

=4.57*10-3*108*109

=4.57*1017*10-3

=4.57*1014s

Therefore frequency of H alpha photon=4.57*1014 s
