answer in millimeters

A macroscopic (or macro) lens for a camera is usually a converging lens of normal focal length built into a lens barrel that can be adjusted to provide the additional lens-to-film distance needed when focusing at very close range. Suppose that a macro lens (f = 53.0 mm) has a maximum lens-to-film distance of 271 mm. How close ca ...continues

What is the height (including sign) of her image on the film

A camera is supplied with two interchangeable lenses, whose focal lengths are 35.0 and 150.0 mm. A woman whose height is 1.80 m stands 7.00 m in front of the camera. What is the height (including sign) of her image on the film, as produced by a 35.0-mm and 150.0-mm lens?

In the old west, a marshal riding on a train traveling 50m/s sees a duel between two men standing on the earth 50m apart parallel to the train. The marshal's instruments indicate that in his reference frame the two men fired simultaneously. (a) Which of the two, the first one the train passes (guy A) or the second (guy B), shoul ...continues

Find the angles that locate the first, second and third-orders.

A Young's double-slit experiment is performed using light that has a wavelength of 615 nm. The separation between the slits is 5.5e-5 m. Find the angles that locate the first, second and third-orders.

A layer of transparent plastic (n = 1.59) on glass (n = 1.52) looks dark when viewed in reflected light whose wavelength is 570 nm in vacuum. Find the two smallest possible nonzero values for the thickness of the layer.

Find the angle that locates the second dark fringe when the wavelength of the light is 445nm and 655 nm.

A single slit has a width of 1.5 10-6 m and is used to form a diffraction pattern. Find the angle that locates the second dark fringe when the wavelength of the light is 445nm and 655 nm.

Determine how far apart two cars must be on the ground if you are to have any hope of distinguishing between them with the following lighting.

You are looking down at the earth from inside a jetliner flying at an altitude of 9300 m. The pupil of your eye has a diameter of 2.00 mm. Determine how far apart two cars must be on the ground if you are to have any hope of distinguishing between them with the following lighting. red light (wavelength = 665 nm in vacuum)and vio ...continues

What is the wavelength of the light shining on the grating?

A diffraction grating produces a first-order bright fringe that is 0.0934 m away from the central bright fringe on a flat screen. The separation between the slits of the grating is 4.27 10-6 m, and the distance between the grating and the screen is 0.625 m. What is the wavelength of the light shining on the grating?
