A laser (light amplification by stimulated emission of radition ) provides a coherent (in phase) monochoramtic source of high intensity light . Lasers are used in eye surgery,CD/DV players basic research etc. Some modern eye lasers can be "tuned" to emit a desired wavelenght . The following table shows the lambda=(nm),v(s^(-1)) and E(J) but some of the date missing : [Take E(ev)=(1240)/lambda_(nm)] {:("Leser No.",lambda("nm"),v(s^(-1)),"Energy (J)"),("I",A,5xx10^(-14),B),("II",487.9,C,D),("III",E,F,3.2xx10^(-19)):} Which of the following statements(s) is /are correct? (i) All the three radiation (from laser ) lie in visble region (ii) The enegies D and B alone are not sufficient to remove electron completely from isolated gaseous H-atoms which is present at ground state (iii) In the spectrum the increasing order of lambda for the type of lasers is IIltIIIltI (iv) None of the above statement is correct
