Experiment 2:reflection EQUIPMENT NEEDED: -Transmitter -Goniometer -Receiver -Metal Reflector -Rotating Component Holder Procedure 1.Arrange the equipment as shown in figure 2.1 with the Transmitter attached to the fixed arm of the Goniometer.Be sure to adjust the Transmitter and Receiver to the same polarity, the horns should have the same orientation as shown. 2.Plug in the Transmitter and turn the Receiver INTENSITY selections switch to 30X. 3.The angle between the incident wave from the Transmitter and a line normal to the plane of Figure 2.1 Equipment Setup the Reflector is called the Angle of incidence (see Figure 2.2).Adjust the Rotating Component Reflector holder so that the Angle of Incidence. 4.Without moving the Transmitter or the Reflector, rotate the movable axis of the Goniometer until Angle of Incidence the meter reading is a maximum.The angle Angle of between the axis of the Receiver horn and a line Reflection normal to the plane of the Reflector is called the Figure 2.2 Angles of Incidence and Reflection Angle of Reflection. 5.Measure and record the angle of reflection for each of the angles of incidence shown in Table 2.1. Table 2.1 Angle of Angle of Incidence NOTE:At various angle settings the Reflection Receiver will detect both the reflected wave 20 30 and the wave coming directly from the 40 Transmitter,thus giving misleading results. 50 Determine the angles for which this is true and 6 70 mark the data collected at these angles with an 80 asterisk " 904 Experiment 2: reflection EQUIPMENT NEEDED: -Transmitter -Goniometer -Receiver -Metal Reflector -Rotating Component Holder Procedure 1.
