How many bright fringes will be seen
WebDec 9, 2024 · The number of bright fringes formed by the blue light will 11. The wavelength of the blue light is given to be 465mm and after passing through the interference grating of slit spacing of 0.003mm it makes an interference pattern on the wall. Now, the number of bright fringes formed on the wall can be founf by using the relation, dsinA = m/y Where, WebSep 12, 2024 · Recall that N − 2 secondary maxima appear between the principal maxima. We can see there will be an infinite number of secondary maxima that appear, and an infinite number of dark fringes between them. This makes the spacing between the fringes, and therefore the width of the maxima, infinitesimally small.
