In a young's double-slit experiment the wavelength of light used is 466 nm (in vacuum), and the separation between the slits is 1.3 × 10^-6 m. determine the angle that locates: (a) the dark fringe for which m = 0 (b) the bright fringe for which m = 1 (c) the dark fringe for which m = 1 and (d) the bright fringe for which m = 2.

Part a)

Part b)

Part c)

Part d)

Explanation:

For the position of dark fringe the path difference of light is odd multiple of half of the wavelength

so here we will have

part a)

for m = 0 we have

Part b)

Similarly for the maximum intensity we will have path difference must be integral multiple of wavelength

so we have

for m = 1 we have

Part c)

for m = 1 we have

Part d)

for m = 2 again we have

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

v=ir = 3x15 =45 v
