- Calculate the width the interference fringe in the middle of the screen between two slits given the wavelength of the incident light is 444 nm and the distance between the slits is 0.013 mm. Take the distance between the slits and the screed D=1 m. Provide your answer in millimetres (mm).Consider a two-slit experiment in which the slit separation is 2.4 x 10-5 m and the interference pattern is observed on a screen that is 1.50 m away from the slits. The wavelength of light passing through the slits is 420 nm. What is the position of the second dark fringe? Show your calculationsTwo slits separated by 0.10 mm are illuminated with green light (2 = 540 nm). Calculate the distance (in cm) from the central bright-region to the fifth bright band if the screen is 1.0 m away. O 2.1 2.7 O 2.5 2.3 2.0
- A laboratory experiment produces a single-slit diffraction pattern on a screen. If the slit is made wider, the bright fringes will beCoherent red light (wavelength 650 nm) is shined on a Young's double slit apparatus. What slit size gives a 5th order interference bright fringe at the first diffraction minimum on a view screen 2 meters away from the slits? Suppose the slit separation is 0.1 mm Can you please show all the steps thank youWhat is the separation on the screen between the first order interference fringes of the two different patterns
- Green light (555nm) is normally incident on a pair of slits which are 12 micrometers apart. How many interference fringes will there be? (Could you please draw a picture as well? Thanks!)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!
- Calculate the width the interference fringe in the middle of the screen between two slits given the wavelength of the incident light is 565 nm and the distance between the slits is 0.011 mm. Take the distance between the slits and the screed D=1 m. Provide your answer in millimetres (mm).- Light of wavelength 572 nm illuminates a single 0.77 mm wide slit. At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 2.08 mm from the central maximum? - What is the width of the central maximum?
