The only element in the hydrogen atom resides under ordinary condition on the first orbit .When energy is supplied the element move to higher energy orbit depending on the lower of energy absorbed .When this electron to may of the electron return to any of the lower orbits, it emit energy Lyman series is formed when the electron to the lowest orbit white Balmer series ids formed when the electron returns to the second orbit similar Paschen Brackett, and Pfund series are formed when electron return to the third fourth , and fifth orbit from highest energy orbits, respectively
Maximum number of liner produced is equal when as electron jumps from nth level to ground level is equal to `(n(n - 1))/(2)`If the electron comes back from the energy level having energy `E_(2)` to the energy level having energy `E_(1)` then the difference may be expressed in terms of energy of photon as `E_(2) - E_(1) = Delta E, lambda = hc//Delta E` Since h and c are constants `Delta E` corresponding to definite energy , thus , each transition from one energy level to another will produce a light of definite wavelength .This is actually observed as a line in the spectrum of hydrogen atom Wave number of line is given by the formula `bar v = RZ^(2)((1)/(n_(1)^(2))- (1)/(n_(2)^(2)))`Where R is a Rydberg constant
The difference in the wavelength of the second line is Lyman series and last line of breaker series is a hydrogen sample is

Options

A. By a black line
B. By a white line
C. By a black line in the lower wavelength range and by a white line in the higher wavelength range
D. By a white line in the lower wavelength range and by a black line in the higher wavelength range.

Answer

A

Explanation

In the spectrum, the wavelength corresponding to the absorbed photons is observed as black lines.
