Dropbox 1. Two point sources are separated by 20 cm. They are producing a node 150 cm away (measured from the centre point between the sources). (a) Determine the distance from the right bisector to the first node if the wavelength is 1.0 cm. (b) Determine the angle between the right bisector and the second nodal line? If the distance from one point source to a point on the second nodal line is 5.0 cm, determine the distance from the other point source to the same point. Assume that it is less than 5 cm. 2. Light of wavelength 650 nm enters kennedium (n−1.57) at an angle of 15° from air. Determine the following: (a) the wavelength of the light in kennedium. (b) the velocity of light in kennedium. (c) the change in frequency of the light as it enters kennedium.
