AI Thread Summary
To compute the energy of the highest energy photon in the hydrogen spectral series (Lyman, Balmer, Paschen, and Brackett), first determine the shortest wavelength for each series. Once the wavelengths are known, calculate the frequency using the formula frequency = speed of light / wavelength. The energy of the photons can then be found using the equation E = h * frequency, where h is Planck's constant. Finally, convert the energy from joules to electron volts using the conversion factor 1 eV = 1.602 x 10^-19 J. This method will yield the required energy values for each spectral series.

Hi,
i have a question...

compute the shortest wavelength in each of these hydrogen spectral series: Lyman, Balmer, Paschen, and Brackett. (which i managed...)

my problem is with the second part of the question : compute the energy in electron volts of the highest energy photon produced in each series.

any suggestions? :-/

Thanks !

You have the wavelenght, then you can calculate the frequency. After that you calculate the energy of the photons of each series. Then "translate" the energy into electron volts.
 
1 eV = 1.602x10^-19 J , i think this will help u to conver
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
