SUMMARY
The discussion centers on calculating the angle subtended by an image when using a 270-diopter objective lens compared to a 140-diopter lens. The anatomist initially observes an angle of 3.7 x 10-3 radians with the 140-diopter lens. By applying the magnification ratio of the objectives, the angle subtended with the 270-diopter lens is determined to be approximately 0.0019185 radians. The small angle approximation is valid, confirming that the image magnification directly correlates with the objective's refracting power.
