The adjacent side is the screen distance of 220cm The opposite side is the distance between the central beam and the 1 st minima = 6.5cm = = - 69 . 1 220 5 . 6 sin 220 6.5 = Sin 1 Slit width, a = ? Diffraction order, p = 1 Wavelength, = 590nm = 0.59m Diffraction angle, = 1.69 m a a a p a 20 69 . 1 59 . sin 59 . 1 69 . 1 sin sin 1 = = = =- Therefore slit width = 20m David McEwen S0091331 2 Question 2 - Specific Heat To find what the ring is made from we need to find the specific heat capacity of the ring, c. The total weight of the full glass was 330g so to find the weight of the glass the weight of the water (225g) was taken from 330g to find the glass weight of 105g....
