The ration of resolving powers of an optical microscope for two wavelangths lamda_(1) =4000 Å and lamda_(2)=6000 Å is

The ratio of resolving powers of an optical microscope for two wavelengths lambda_1 =4000overset@A and lambda_2= 6000overset@A is

Bichromatic light of wavelengths lambda_1= 5000Å and lambda_2=7000Å are used in YDSE. Then,

Bichromatic light of wavelengths lambda_1= 5000Å and lambda_2=7000Å are used in YDSE. Then,

In YDSE a parallel beam of incident light consists of two wavelengths lambda_(1)=4000Å and lambda_(2)=5600Å . The minimum distance y on the screen, measured from the central axis, where the bright fringe due to two wavelengths coincide is (nlambda_(1)D)/(d) . Find n.
