Monochromatic Light Of Wavelength D Is Incident On A Pair Of Sits Separated By 2 70 X 10 M And Forms An Interference Pat 1 (30.66 KiB) Viewed 36 times

Monochromatic light of wavelength d is incident on a pair of sits separated by 2.70 x 10 m and forms an interference pattern on a screen placed 1.50 m from the slits. The first-order bright fringe is at a position Yorone - 4.46 mm measured from the center of the central maximum. From this information, we wish to predict where the fringe for n-50 would be located (a) Assuming the fringes are tald out linearly along the screen, find the position of the n - 50 fringe by multiplying the position of the n = 1 fringe by 50.0 m (b) Find the tangent of the angle the first-order bright fringe makes with respect to the line extending from the point midway between the slits to the center of the central maximum (c) Using the result of ppt (b) and dsin pright = mà, calculate the wavelength of the light. nm (d) Compute the angle for the oth-order bright fringe from sin right mi (e) Find the position of the 50th-order bright fringe on the screen from Voright tanbright m (0) Comment on the agreement between the answers to parts (a) and (e),
