Two slits of width 2μm, each in an opaque material, are separated by a center-to-center distance of 6μm. A monochromatic light of wavelength 450 nm is incident on the double-slit. One ﬁnds a combined interference and diffraction pattern on the screen. A) How many peaks of the interference will be observed in the central maximum of the diffraction pattern?B) How many peaks of the interference will be observed if the slit width is doubled while keeping the distance between the slits same?C) How many peaks of interference will be observed if the slits are separated by twice the distance, that is, 12 μm, while keeping the widths of the slits same?D) What will happen in (a) if instead of 450-nm light another light of wavelength 680 nm is used?E) What is the value of the ratio of the intensity of the central peak to the intensity of the next bright peak in (a)?F) Does this ratio depend on the wavelength of the light?G) Does this ratio depend on the width or separation of the slits?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
