A red light wave has a frequency of 4.62x10\" Hz and a speed of 3.0x108 m/s through air. If the red light passes from the air into a glass window. .. This questions covers the Wave Nature of Light unit and expectations [E22, E23, E3.2, E33] a) What will be the speed of the red light throlugh the glass? [K/U] /2 marks (r'lair= 1-00: r1glass= 152) b) Now if that same red light passes through a beaker (nbeake, = 1.52) containing a thin walled cleatr test tube in which both the beaker and test tube (ntt = 1.52) are filled with the same liquid (nnquid: 1.52). Explain what you will observe and fully explain why you would observed this. [APPS] /5 marks
