 Lab Equipment  Directions
  1.  Microwave transmitter with pulg in cord and microwave receive mounted on board
  2. 4 metal gratings (2 round, 2 ‘square’)
Optional: Connect Fluke 8000 (set to DC volts and range 20) to receiver with 2 BB
  1.  Plug RCA end of cord into back of transmitter. (Red light should glow when plugged into wall).
  2. Turn sensitivity knob on receiver to low. Adjust intensity knob to 30x setting. Increase sensitivity knob as needed to obtain approximately a half-scale deflection.
  3. Insert square grating between transmitter and receiver with slits vertical. Then rotate grating 90 degrees.
  4. Insert second grating between first grating and transmitter at 0 degrees, 90 degrees, 45 degree angle to first.
  5. Use the round gratings to show the effect of slit size to wavelength ratio.
