Q 25 An electron microscope is operated at 40 KV The ratio of
resolving power of this microscope and another one which uses
yellow light of wavelength 6 × 10 -7 m is (1) 9 73
× 106 (2) 9 78 × 104 (3) 9 78
× 10-4 (4) 9 78 × 10-6

Dear student,The resolving power of a microscope is inversely proportional to the wavelength of light used
For first electron miscroscope,λ=h2meEλ=6
6×10-342×9 11×10-31×1
6×10-19×40×103=3
5×10-10mfor second microscope,λ'=cν=3×1086×10-7=0
5×1015mλλ'=3 5×10-100
5×1015=7×10-25This will be the ratio of resolving power of two microscope
Please check the given options may be there is an error
 Regards
