6. Lens 1 has a focal length of 5.00 cm and lens 2 has a focal length of 4.00 cm. Lens 1 is placed 6.00 cm to the left of Lens 2. A 2.00 cm tall object is placed a distance of 13.0 cm to the left of lens 1. (a) With respect to the location of lens 1, where is the image produced by lens 1? (b) With respect to the location of lens 1, where is the image...
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?
2. A telescopic lens consists of a convergent lens of 5 cm focal length and 5 cm in diameter placed 4 cm in front a divergent lens of focal length -8 cm and diameter 4cm. In addition, a stop ween the lens 2 em from the convergent lens with a diameter of 3 cm. Determine the aperture stop, the limiting entrance and exit pupils for an object 35 em away from the convergent lens. Find positions and diameters. system. b)...
When a diverging lens is held 13.0 cm above a line of print, as in Figure 26.29, the image is 5.0 cm beneath the lens. (a) Is the image real or virtual? (b) What is the focal length of the lens?
One lens has a focal length of +15.6 cm. A second lens of focal length +21.1 cm is placed in contact with the first lens. What is the equivalent focal length of the combination of lenses?
A magnifying glass is a single convex lens with a focal length of ff = 13.0 cm . What is the angular magnification when this lens forms a (virtual) image at the person's near point (assumed to be 25 cm)? M =
Part A Two converging lenses are placed 35.5 cm apart. The focal length of the lens on the right is 19.5 cm and the focal length of the lens on the left is 13.0 cm. An object is placed to the left of the 13.0 cm focal-length lens. A final image from both lenses is inverted and located halfway between the two lenses. How far to the left of the 13.0 cm focal-length lens is the original object? A2 -...
