1.radar uses MICROWAVES to tell the position or speed of objects





False. RADAR (RAdio Direction And Ranging) may use any frequency, not just microwave.











2.an ILLUMINATED object gives of its own light





False. An illuminated object reflects light (photons in the visible range of frequencies).











3.a NEON LIGHT contains a filament and a gas





False. A neon lamp contains two parallel electrodes that ionize the neon gas in its vicinity.











4.when an AM radio station broadcasts,the *FREQUENCY of the wave remains constant





False. Although the carrier frequency does not change, the side bands are modified by the modulation applied to the carrier.











5. if two polarizing filters are placed so that one is rotated 60 DEGREES no light can come through





False. No filter is so good that it produces a hundred percent polarization. There will always be some throughput even if the human eye does not see it. The polarization effect is also wide enough that there will be a significant amount of light at an angle from the intended orientation. The quality of the filters will determine how much light may be detected. The better the quality, the less light.
