Question

a line with a wavelength of 486.4 nm was observed in the Balmer series of the emission spectrum of hydrogen. Determine the initial and final values of the energy levels associated with this emission

Answer 1

(6.626× 10^-34J.S × 2.998 × 10⁸ $\frac{m}{s}$ )/486.4 × 10^-9m

-2.178×10^-18J × 1²(1/2²-1/n²)

6.626 × 10^-34 × J.S × 2.998 × 10⁸

$\frac{m}{s} ​$/486.4 × 10^-9m

n = 4.1
