A compound microscope has an objective lens with a focal length of 0.40 cm and an...
In a compound microscope, the objective has a focal length of 0.48 cm, while the eyepiece has a focal length of 1.9 cm. The separation between the objective and the eyepiece is L = 10.0 cm. Another microscope that has the same angular magnification can be constructed by interchanging the two lenses, provided that the distance between the lenses is adjusted to a value L'. Find L'.
What is the approximate magnification of a compound microscope with objective and eyepiece focal lengths of 0.30 cm and 3.6 cm, respectively, and a separation between lenses of 20 cm? a. 12 b. 20 C. 67 d. 460 A telescope has an objective lens with a focal length of 100 cm and an eyepiece of focal length 3.0 cm. What is the magnification of the telescope? a. +30 b. -33 C. +60 d. -180 20. Page 6 of 6
In a compound microscope, the focal length of the objective is 3.71 cm and that of the eyepiece is 6.60 cm. The distance between the lenses is 17.6 cm. (a) What is the angular magnification of the microscope if the person using it has a near point of 32.1 cm? (b) If, as normal, the first image lies just inside the focal point of the eyepiece, as in the drawing, how far is the object from the objective? (c) What...
A compound microscope has an objective lens of focal length 10.0 mm with an eyepiece of focal length 15.5 mm , and it produces its final image at infinity. The object to be viewed is placed 2.0 mm beyond the focal point of the objective lens. a. How far from the objective lens is the first image formed? b. What is the overall magnification of this microscope?
A compound microscope has an overall length of 25cm. If the objective lens has a linear magnification of 20 and the eyepiece has an apparent magnification of 10, what are their focal lengths? How close to the objective lens should be placed for viewing the final image? What is the total magnification?
A microscope has an objective lens of focal length 00 mm. The objective forms an image 18 cm from the lens. The focal length of the eyepiece is 70 cm. What is the distance between the lenses?
A compound microscope has objective and eyepiece lenses of focal lengths 0.80 cm and 4.0 cm, respectively. If the microscope length is 15 cm, what is the approximate magnification of the microscope?
The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscope is to provide an angular magnification of -88 when used by a person with a normal near point (25 cm from the eye), what must be the focal length of the eyepiece?
The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscope is to provide an angular magnification of -64 when used by a person with a normal near point (25 cm from the eye), what must be the focal length of the eyepiece?
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.
