    In the hydrogen spectrum, a line with a wavelength of 410.3 nm is found. (a) what color is the line (b) what is the frequency and (c) what is the energy of the photons.


    Answer: 


    (a) because of the wavelength of 410,3 nm the corresponding spectrum of hydrogen has a purple color.


    (b) F = c/wavelength 


    = (3.00 x 108 m/s)/(410,3 x 10-9 m)


    = 0,0073 x 1017 Hz


    = 73 x 1013 Hz


    (c) E = h x F


    E = (6,6 x 10-34 J.s) x (73 x 1013 Hz)


    E = 481,8 x 10-21 J


    E = 48,18 x 10-20 J
