The power of our microwave transmitters is about 15 mW. What is the approximate power of a typical microwave oven? power? v
If, when you set up one of the interference experiments, you get zero signal on the detector, which of the following could be the problem?
O You have the sensitivity of the detector set too low.
O You have the power on the transmitter off.
O You have rotated the detector 90° around a horizontal axis (microwaves are polarized).
O One or more of the reflectors is misaligned so that the beam does not reach the detector.
O You just happen to have the reflectors in position to create destructive interference.
O You have mixed up which is the mirror and the partial reflector.
O The equipment doesn't like you today.
O Someone's hand is blocking the beam.
If in one of the first two interference experiments you have a maximum signal on the detector, and you move the mirror 2/2 further back, what will you have then? feature?
The microwave transmitters that we use have a frequency of about 10 GHz. What is the approximate wavelength?

- Light of intensity I0 passes through two sets of apparatus. One contains one slit and the other two slits. The slits have the same width. What is the ratio of the out going intensity amplitude for the central peak for the two-slit case compared to the single slit?arrow_forwardMalus's Law Below is an image of light with initial intensity lo = 750.0 W/m² going through 2 polarizing filters. The first polarizing filter is oriented with vertical polarization. The angle between the two polarizing filters is 0 = 35.0 degrees. The light is initially polarized horizontal before entering the first polarizing filter. What is the intensity of the light at l, (after passing through both filters)? Make sure to give your answer in units of W/m² and with an appropriate number of significant figures. Polarizing Filter, Polarizing Filter, Io 12 Your Answer: Answerarrow_forwardPolarized light passes through two rotated filters from left to right, as shown. At the point A, its intensity is Io. The polarization axis of the first polarizer makes an angle 01= 52.6° with the direction of polarization the incoming light. The polarization axis of the second polarizer makes an angle 02= 59.6° degrees with the polarization axis of the first polarizer.
