A laser ( light amplification of stimulated emission of radiation ) provides a coherent( in phase ) nearly monochromatic source of high intensty light. Lasers are used in eye surgery, CD // DVD players basic research, etc. some modern eye lasers can be "tuned" to emit a desired wavelength. The following table shows the lambda( nm ) , v( s^(-1))andE ( J) but some of the data is missing : If an electron absorbs energy equal to D in hydrogen atom in first excited state and after reaching highest excited level it returns to ground level. How many possible lines will be obtained in hydrogen spectrum?

1.	A laser ( light amplification of stimulated emission of radiation ) provides a coherent( in phase ) nearly monochromatic source of high intensty light. Lasers are used in eye surgery, CD // DVD players basic research, etc. some modern eye lasers can be "tuned" to emit a desired wavelength. The following table shows the lambda( nm ) , v( s^(-1))andE ( J) but some of the data is missing : If an electron absorbs energy equal to D in hydrogen atom in first excited state and after reaching highest excited level it returns to ground level. How many possible lines will be obtained in hydrogen spectrum?
