Answer the following: (a) If one of two identical slits producing interference in Young's experiment is covered with glass so thatthe lightintensity passing through it is reduced to 50%, find the ratio of the maximum and minimum intensity of the fringe in the interference pattern. (b)Whatkindof fringes do you expect to observeif white lightis used instead of monochromatic light ? |

Answer» SOLUTION :After the introduction of the glass SHEET (SAY on the second slit ) . We have ` (I_2)/( I_2) =50% =(1)/(2) ` ` therefore ` Ratio of the AMPLITUDES ` = ( a_2)/(a_1)=sqrt( (1)/(2) ) =(1)/(sqrt(2)` |
