If our eyes could see a slightly wider region of the electromagnetic spectrum, we would see a fifth line in the balmer series emission spectrum. calculate the wavelength λλlambda associated with the fifth line.

λ = 397 nm

Explanation:

given,

Rydberg wavelength equation for Balmer series

R is the Rydberg constant, R = 1.097 x 10⁷ m⁻¹

n_i = initial energy level  

n_f = final energy level

where as for Balmer series n_f = 2

            n_i = 7

Hence, the wavelength is equal to  λ = 397 nm

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
