Jamie's far point is 30 cm from her eye, and her near point is 10 cm from her eye. To correct her vision, Jamie needs glasses that create an image of distant objects that is O at her near point. 0 at infinity. 0 25 cm from her eye. 0 at her far point. A microscope has an objective lens whose refractive power is 30 D and an eyepiece lens of the refractive power of is 60 D. What is the total magnification of this microscope? The length of the microscope is 160 mm. l ] ., A light of wavelength 650 nm is incident on a diffraction grating. A second maximum is located at 54.0 cm above the central maximum on a viewing screen located at 2.50 m from the grading. Find the line slit separation in micrometers (1 pm = 10'6 m)
