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, WebAdvanced Physics questions and answers.
