1 The wavelength of a light source shining through a single-slit of width 2.34 x 105 m is 625 nm. If the screen is 4.44 m away, how far is it from the second minimum on the right to the third minimum on the left? 2 What is the ratio of the width of the central maximum to the distance between the first and third minimum fringes on one side? 3 The wavelength of a light source shining through a single-slit of width 4.34 x 10 5 m is 525 nm. If the screen is 2.44 m away, how far is it from the centre of the central maximum to the second minimum? 4 The screen for problem three is shown below. Mark on the screen the locations for the first two minima on each side of the central maximum. sriman [ top view. ) centre 5 The angular width of the central maximum is 28.4". If a light source of 1 = 616 nm shines through the single-slit determine the width of the slit
