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.
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.
Equipment: Example lens (magnifying, reading glasses, or eyeglasses for a farsighted person), a small hand mirror, blank paper; straight edge (ruler)
What are the two minimum thicknesses that will constructively reflect visible light with = 676 nm?
When a beam of white light passes perpendicularly through a flat pane of glass, it is not dispersed into a spectrum. Why not?
A diffraction grating has slits ruled on opaque material and has 20 slits per mm. The distance between the slit centres is twice the width of each slit.
A thin double convex lens of focal length f = +15 centimeters is located at the origin of the x-axis
A mixture of yellow light (wavelength = 582 nm in vacuum) and violet light (wavelength = 414 nm in vacuum) falls perpendicularly on a film of gasoline
Two identical prisms made of dispersive glass, are placed as shown and a narrow beam of white light enters from the left. If the prisms are in the configuration
How significant is the broadening of a nsec pulse laser in the optical fibers? Their fiber was quartz, 2.5 m long, 600 um in diameter, with numerical aperture
A parallel beam of light is incident on the surface of a transparent hemisphere of index 2.0 at an angel of 45 degrees to the axis.
An object of height 5 cm is placed 30 cm in front of spherical concave mirror. If the image is real and 10 cm high, what is the radius of curvature

An object is midway between the biconcave lens (with focal length -16.7 cm) and the concave mirror (with radius of curvature 20 cm).
Two rectangular optically flat plates (n=1.52) are in contact along one end and are separated along the other end by a 2.00 micrometer thick spacer
The figure shows four long horizontal layers of different materials, with air above and below the stack. The index of refraction is given for each layer
An object is placed 12.0 cm in front of a converging lens of focal length 5.00 cm. A concave mirror with radius of curvature 20.0 cm is located 30.0 cm
Images in a very thick glass mirror may by slightly colored by dispersion. Draw two vertical lines, separated by about 2 cm
