Optics: Double-Slit Arrangement

In a double-slit arrangement the slits are separated by a distance equal to 100 times the wavelength of the light passing through the slits. (a) What is the angular separation in radians between the central maximum and an adjacent maximum? (b) What is the distance between these maxima on a screen 50.0 cm from the slits?

Optics, magnification, etc

Please help with 48, 56, 62, 72, 86 ONLY 48) What is the magnification of the object when the object is 35 cm from the lens (see attachment please)

Optics - Lens Power

Reading glasses of what power (D) are needed for a person whose near point is 121cm, so that he can read a computer screen at 48.8cm? Assume a lens eye distance of 1.83cm.

Geometrical Optics

A small insect is placed 5.41cm from a +6.59cm focal length lens. Calculate the position of the image. Calculate the angular magnification.

Electronic and Optoelectronic Devices

1. A microscope has an objective with f = 1 cm, an ocular with f = 2.5 cm, and a distance s = 10 cm between them. Taking the best viewing distance as 25 cm, a) Find the magnification of a microscope b) Plot the picture of the rays to scale using the graph paper. 2. Model a parabolic graded-index fibre with n (r) = n 1 [1-(r

Geometrical Optics: Form images with a plane mirror; minimum height of mirror

You are 1.8 m tall and stand 3.0 m from a plane mirror that extends vertically upward from the floor. On the floor 1.5 m in front of the mirror is a small table, 0.80 m high. What is the minimum height the mirror must have for you to be able to see the top of the table in the mirror? Please include what law is used to solve.

Optics: Application of the lens formula.

A slide projector produces a 500 times enlarged image of a slide on a screen 10m away. If the screen is moved 2m closer, by what distance should the slide be moved towards or away from the lens so that the image remains focused on the screen? What is the magnification in this case? Assume that the projector consists of a single

Physical optics

Multiple choice: 1. The middle of the first-order maximum, adjacent to the central bright fringe in the double-slit experiment, corresponds to at a point where the optical path length difference from the tow apertures is equal to: (a) h (=lander) (b) 0 (c) 1/2h (d) 1/4h (e) none of the above. Explain your choice. 2. A narrow

Physical optics

In an experiment where you light a long filament vertical light bulb. If you look at it from several meters away through a vertical slit cut in a 3 X 5 card, you will see a lovely fringe system. Explain what's happening. Multiple choice: 1. Light linearly polarized in the plane-of-incidence impinges on the surface of a glass

Physical Optics are examined.

Q: If you put a few drops of liquid in a cup of soap with a little water and shake it around, making a great froth of bubbles. After several seconds, the bubbles will begin to show bright rainbow color patterns. Why must you wait before the colors appear? Q: If you take a very close look at a worn surface under direct sunligh

Optics are emphasized.

1. A point source of light lies on the central axis of a bi-convex spherical lends who radii of curvature are both measured to be 19.4 cm. The lens is made up of glass with an index of refraction of 1.50 and the source is 3.17 meters to the left of it. What is the image distance (in meters)? 2. A grasshopper sitting 31.4 cm t
