The limit of resolution of an oil immersion objective microscope of numerical aperture 0.8 for light of wavelength (0.6 m ) is
Options
- A( 1.5 8 m )
- B( 3 8 m )
- C( 5 8 m )
- D( 7 8 m )
Correct answer
B. ( 3 8 m )
Step-by-step solution
Numerical aperture, (N A=0.8 ) Wavelength, ( =0.6 m ) ( ) Limit of resolution (= 2 N A = 0.6 2 0.8 = 0.3 0.8 = 3 8 m )
