part 1: A lens is held horizontally to form an image of an object on the ground. You observe that the image is formed above the lens. is the image virtual, inverted, or concave lens?

part 2: Two two-slit experiments are done separately in two mediums to study the effect that medium has on the interference. Each medium has the different indices of refraction, m and n, where m > n. In which medium are the interference fringes closer, if at all? is it m, n, fringes have the same distance or none?

Please answer all Parts. Will rate up! Thanks! Part A: Two slits have a separation, 7.12×10−3 m. An interference pattern is created 5.46 m away from the slits, with a distance 0.832 m between the central bright fringe and the 9th dark fringe below it. What is the wavelength of light used to create the pattern? 1.79×10−4 m 4.77×10−4 m 0.762 m 1.26×10−4 m Part B: Two two-slit experiments are conducted separately in two mediums to study the effect that...

Because a concave lens cannot form a real image of a real object, it is difficult to measure its focal length precisely. One method uses a second, convex, lens to produce a virtual object for the concave lens. Under the proper conditions, the concave lens will form a real image of the virtual object! A student conducting a laboratory project on concave lenses makes the following observations: When a lamp is placed 42.7 cm to the left of a particular...

A single bi-concave lens (a lens with two concave surfaces) made of glass (index of refraction n = 1.55) has surfaces with radii of curvature r1 = -19.0 cm and r2 = 19.0 cm. What is the focal length of the lens in air? I got 17.32cm as the correct answer. Dont know the other two. If an object is placed at p = 20.0 cm from the lens, where is the image? (Use a positive sign for a real...

1) Two convex lenses, both with focal length 1.5 m, are placed such that the light from a 4 cm tall object passes through each. The object is placed 4.5 m from the first lens, and the lenses are 3 m apart. Where will the image from the first lens be? Will it be real or virtual? Will it be upright or inverted? Where will the final image be (using both lenses)? Will it be real or virtual? Upright or...
