a. Find the distance from the centre of the central maximum to the first minimum. b. Find the width of the central maximum in metres. c. Find the width of the central maximum in radians. d. If the wavelength is increased by a factor of 1.50 does the distance from the centre of the central maximum to the first minimum go up by the same factor? Calculate this distance just to make sure. 2 The distance from the centre of the central maximum to the third minimum is 0.0128 m. If the width of the slit is 3.42 x 105m and the wavelength of the light is 555 nm, find the distance from the slit to the screen
