WAVES Task1 The principle of superposition states that when two waves of the same type cross, the displacement at any point is equal to the vector sum of the displacements of each of the waves at that point. Wave crest + wave crest = supercrest Wave trough + wave trough = supertrough Wave crest + wave trough = cancellation Task 2 Aim To carry out a two source superposition of laser light experiment using a double slit, and determine the wavelength. Method * The laser is set up on a level bench and plugged in. * A screen is set up at least 2 metres away. * Graph paper is attached to the screen. * A double slit(s) is positioned in front of the laser. * The laser is turned on and due to safety precautions should not be directly looked at as it can cause damage to the eye. * The positioning of the laser is adjusted till the laser is visible on the...
