Here, we use the concept of normal magnification and maximum magnification to get the answer of both the parts.
13. What is the maximum magnification that is possible with a lens having a focal length...
(a) What is the maximum angular magnification of an eyeglass lens having a focal length of 19.6 cm when used as a simple magnifier? (b) What is the magnification of this lens when the eye is relaxed?
The focal length of a lens is 4.5 cm. Calculate the maximum angular magnification of a simple magnifier when the image is formed at the normal near point of the eye.
The focal length of a lens is 4.6 cm. Calculate the maximum angular magnification of a simple magnifier when the image is formed at the normal near point of the eye.
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?
A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...
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?
7. A magnifying lens with a focal length of 10 cm has what magnification if the image is at the near point of 25 cm? SI
Two lens with different focal length are made as a telescope. If the magnification is 16 and the length of telescope is 85 cm, how much is the focal length of eye lens?
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?
Sherlock Holmes is using an 8.90-cm-focal-length lens as his magnifying glass. a) To obtain maximum magnification, where must the object be placed (assume a normal eye)? Express your answer using two significant figures and include the appropriate units. b) What will be the magnification? Express your answer using two significant figures.
