QUESTION 19 Why can't a light microscope be used to visualize objects smaller than - 200 nm? O A. The image formed is virtual and therefore can't be seen O B. The objects are smaller than the resolving power due to diffraction Objects smaller than 200 nm are opaque to visible light O D. Lenses can't be made large enough to minimize refraction O E. The objects would appear in the "circle of confusion" OC.
QUESTION 20 A nearsighted person needs what kind of corrective lenses? What do these lenses do? OA. Diverging lenses; bring near objects to the near point OB. Converging lenses; bring far objects to the far point O C. Diverging lenses; bring far objects to the far point OD. Converging lenses; bring near objects to the near point OE. Telescopic lenses; bring far objects to the far point
