- Light with wavelength i passes through a narrow slit of width w and is seen on a screen which is located at a distance D in front of the slit. The first minimum of the diffraction pattern is at distance d from the middle of the central maximum. Calculate the wavelength of light if D=3.1 m, d=1 mm and w = VAD. Give your answer in nanometers. Answer: nm Next pageLight with a wavelength is 600 nm passes through a slit and makes the intensity pattern shown in the figure on a screen that is 2.5 m from the slit. Based on this pattern, is the aperture a single slit or a double slit? Explain. If the aperture is a single slit what is the width? If it is a double slit, what is the spacing between the slits.If the wavelength of light used in Young's double slit experiment is decreased, which one of the following statements is true of the interference pattern? O The distance between the minima stays the same. The distance between the maxima decreases. The distance between the minima increases. The distance between the maxima stays the same.
- Please asapWrite down an expression for the highest order mof diffraction in a double slit experiment if the distance between the slits is a and slits are illuminated with light of the wavelength . Please use "*" (without the quotes) for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "- "signs as appropriate. For exponents (e.g. A²) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acose use A*cos theta. Please use the "Display response" button to check you entered the answer you expect. Answer: Display responsePart (a) What is the ratio of the slit width to the wavelength of the incident light? Part (b) What is the wavelength of the incident light, in nanometers?
- What would you observe if you made the slit separation very very large (assuming you still had a coherent source that could still pass through both slits). Comment on how this is different from the single slit experiment.A student acquired a thin filter that transmits only half the incoming intensity, and he puts this filter in front of one of the slits in a double-slit experiment. What will happen to the fringes on the screen? The answer is that bright fringes become darker and dark fringes become brighter. Please explain why, in a way that someone who knows little physics would understand. Thank you!The figure below shows the interference pattern obtained in a double-slit experiment with light of wavelength λ. Select the fringe or fringes that result from the interference of two waves whose paths differ by exactly 2λ. A B C D E
