Table 2. Radiation rates at 7. Then, by placing the sensor consistently in front of black, then dull power setting of #4.0 aluminum, polished aluminum and white surface, record the radiation sensor reading in Table 2. Surface Vo m V 8. Place the sensor in the area labeled "Sensor Location" and block the Black front of the sensor with the foam sheet. Dull 9. Change the power setting to the next one listed in Table 1 and wait until Aluminum the cube reaches thermal equilibrium 71.~ 10-15 min?i and, just for black Polished surface, repeat measurements of Aluminum record its values in Table 1.
