wat are the numbers for magnification of objective lens?
There are 3 to 4 objective lens present in microscope.
They are of following power:
4X (sometimes 5X), 10X, 40X, 100X.
The objective lens and the eyepiece of a microscope are 16.5 cm apart. The objective lens has a magnification of 61× and the eyepiece has a magnification of 10 ×. Assume that the image of the objective lies very close to the focal point of the eyepiece. A. Calculate the overall magnification of the microscope. B.Calculate the focal length of the eyepiece. C. Calculate the focal length of the objective.

Part A: What is the magnification of an astronomical telescope whose objective lens has a focal length of 71cm and whose eyepiece has a focal length of 2.9cm? Follow the sign conventions. Part B: What is the overall length of the telescope when adjusted for a relaxed eye?
What is the magnification of a telescope which has an objective lens of focal length 2.50 m and a diameter of 1.00 m, and an eyepiece of focal length 4.50 cm? What is the angular resolution of this telescope for visible light (wavelength = 550 nm)? What is the length of the telescope?
Part A What is the magnification of an astronomical telescope whose objective lens has a focal length of 73 cm and whose eyepiece has a focal length of 2.6 cm ? Follow the sign conventions. Part B What is the overall length of the telescope when adjusted for a relaxed eye?
Lab Manual Total magnification is calculated by multiplying the magnification of the ocular lens (eyepiece) by the magnification of the objective lens. The magnitication of a lens is imprinted on the lens casing. Total Magnification Observation: Total Magnification Calculate total magnification figures for your microscope, and record your findings in Table 2.3.
