White light passes through many slits separated by 2.00 mm displaying bands of colour on a screen 10.0 m away. a. How wide is the first order band if it contains violet light at 370 nm up to red light at 700 nm? (1 point) b. If the screen is 3.0 m wide how many full bands of coloured light will appear on it? (3 points
