The tube length in a certain compound microscope is 25 cm. The focal length of the objective lens is 2.1 cm. The clearest image is formed when an object of height 1 mm is placed at a distance of 2.3 cm from the objective lens. Determine: (i) The position of the intermediate image, (ii) the focal length of the eye piece, that will place the final image at the near-point, (iii) the total magnification of the microscope and the height of the image, (iv) sketch to scale a ray diagram that verify your findings.

A microscope with an objective of focal length

A microscope with an objective of focal length 1.8 mm is used to inspect the tiny features of a computer chip. It is desired to resolve two objects only 400 nm apart. What diameter objective is needed if the microscope is used in air with light of wavelength 550 nm?

a) A 4.0 cm -tall object is 15 cm in front of a CONVEX mirror that has a -25 cm focal length.

1. Please complete the following parts of the question regarding optics. a) A 4.0 cm -tall object is 15 cm in front of a CONVEX mirror that has a -25 cm focal length. Calculate the image position then Calculate the image height. Type a positive value if the image is upright and a negative value if it is inverted. b) A 3.0-cm-tall object is 17 cm in front of a CONVERGING lens that has a 32 cm focal length....

A microscope has an objective lens with a focal length of 16.22 mm and an eyepiece with a focal length of 9.28 mm. With the length of the barrel set at 31.0 cm, the diameter of a red blood cell's image subtends an angle of 1.43 mrad with the eye. If the final image distance is 31.0 cm from the eyepiece, what is the actual diameter of the red blood cell?

A) The medium-power objective lens in a laboratory microscope has a focal length fobjective = 4.00 mm . If this lens produces a lateral magnification of -37.0, what is its "working distance"; that is, what is the distance from the object to the objective lens B) What is the focal length of an eyepiece lens that will provide an overall magnification of -115? Assume student's near-point distance is N = 25 cm.
