The Balmer series consists of the spectral lines from hydrogen for an electron making a transition from an excited state to the
MaRussiya [10]

Answer:

Wavelength of the first four spectral line:

\lambda_1=1216{\AA}

\lambda_2=1026{\AA}

\lambda_3=972.8{\AA}

\lambda_4=950{\AA}

Explanation:

Lman series when electron from higher shell number and jumps to 1st shell then all the possible lines is called as lyman series.

to calculate wavelength of first four spectral line:

For hydrogen Z=1;

by using rydberg equation

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

1. n=2 to n=1

\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]

\frac{1}{R} =912{\AA} =rydberg constant

\lambda=\frac{4}{3R}

\lambda_1=1216{\AA}

2. n=3 to n=1

\lambda=\frac{9}{8R}

\lambda_2=1026{\AA}

3. n=4 to n=1

\lambda=\frac{16}{15R}

\lambda_3=972.8{\AA}

4. n=5 to n=1

\lambda=\frac{25}{24R}

\lambda_4=950{\AA}

Which of the following best defines the internal energy of a system?
Anarel [89]
 <span>In thermodynamics, the internal energy of a thermodynamic system, or a body with well-defined boundaries, denoted by U, or sometimes E, is the total of the kinetic energy due to the motion of molecules (translational, rotational, vibrational) and the potential energy associated with the vibrational and electric energy of atoms within molecules or crystals. It includes the energy in all the chemical bonds, and the energy of the free, conduction electrons in metals.</span>
