1.The normal human eye has maximum visual acuity with a pupil size of about 3 mm. For larger pupils, acuity decreases due to increasing aberrations; for smaller pupils, acuity decreases due to increasing effects of diffraction. If your pupil diameter is 2.5 mm, as it would be in fairly bright light, what is the smallest diameter circle that you can barely see as a circle, rather than just a dot, if the circle is at your near point, 25 cm from your eye? Assume the light's wavelength in air is soo nm and the index of refraction inside the eye is 1.33. Express your answer with the appropriate units. m [LA-L +5 1".\" c} ? 2. 1four task in physics lab is to make a microscope from two lenses. Doe lens has a focal length of 10 cm, the other a focal length of 4.5 cm. You plan to use the more powerful lens as the objective, and you want its image to be 15 cm from the lens, as in a standard biological microsoopel A. How far should the objective lens be from the object to produce a real image 16 cm from the objective? Express your answer in centimeters. B. What will be the magnification of your microscope? 3. 1With -5.5 DD corrective lenses, Juliana's distant vision is quite sharp. She has a pair of 3.t} DD computer glassa that puts her oomputer screen right at her for point. How far away is her computer? Express your answer with tile appropriate units
