Question

Table #2

color angular position right in degree angular position left in degress average position in degress

red 11.40 11.62 11.51

aqua 8.41 8.73 8.57

violet 7.49 7.67 7.58

A}. find the wavelength if the emission lines of hydrogen listed in above chart

red

aqua

violet

B} determine the energy in (eV) of the photons associated with the wavelength found in setp 12

using this equation Eph=12,400eV[]A/lauma

red

aqua

violet

C} find the absolut percent errors in the measured values of the photon nenergies listd in table 2. with

absolute %error=abs(measured-expected)/expectedX100

calculate

red photon energy error

aqua photon energy error

violet photon energy error

We have formula

sin@ =Nnlamda

Lamda =sin@/Nn

fi(@) is given in the table we have to know the order if first order (n=1) and N is number of lines on the gratingelement

Now we will get the wavelengths for different angular positions

Then using this wavelengths we get energy associated with the photons E ph =12,400eV/Lamda's for three colours individually

Now we need to have the standard wavelength values

If we substitute in the above given formula we will get the % error for each colour
