Laws: Newton’s first law of motion: an object will continue in a state of rest or uniform motion in a straight line unless an eternal force acts upon it. Newton’s second law of motion: the rate of change of momentum of an object is directly proportional to the force acting, and takes place in the direction in which the force acts. Newton’s third law of motion: To every action there is an …showed first 75 words of 448 total…

Young’s Experiment: l = sw/D (s = distance btw centers of parallel slits / D = distance from slits to eyepiece scale / w = distance btw centers of two neighboring fringes)
