In a Young's double slit experiment, two slits act as cherent sources of waves of equal amplitude A and wavelength lambda. In another experiment with the same arrangement the two slits are made to act as incoherent sources of waves of same amplitude and wvaelenght. If the intensity at the middle point of the screen in the first case is I_(1) and in the second case is I_(2) then the ratio (I_(1))/(I_(2)) is : |

Answer» Solution :For COHERENT SOURCES : `I_(1) = 4I_(0)` For coherent sources `I_(2) = 2I_(0)` `(I_(1))/(I_(2)) = (2)/(1)` |
