Achieve question 9

Hi! If someone could help me out with this question that would be great. Thank you so much!

Calculate the wavelength (in nanometers) of the spectral line produced when an electron in a hydrogen atom undergoes the transition from the energy level n = 7 to the level n = 2.

Thank you so much!!

Hi!

For this question in order to calculate the wavelength you'll need to use the equation 1/'lambda' = (1.0974 x 10^7 m) (1/n1^2 - 1/n2^2). From here you need to convert the number into nanometers so you would multiply the answer by (10^9 nm/1 m).

Hope this helps!

The wavelength, of the spectral line observed when an electron in a hydrogen atom drops from a higher energy level n=2 to a lower level n=1 can be calculated using the Rydberg equation for hydrogen. Solve that equation for wavelength to obtain the formula for the wavelength to obtain the answer
