31. In a good conductor of electricity through which the charges move easily, the microwaves are reflected, 32. Salt water, and water with other kinds of impurities in it, is a pretty good conductor . 33. Naturally, the impedance of the earth is far inferior to that of a good conductor ground plane. 34. I had already assumed this to be the case, and that the water was a good conductor . 35. Now, thermal gradients within the sphere become important, even though the sphere material is a good conductor . 36. In 1893, George Francis FitzGerald noted that the upper layers of the atmosphere must be fairly good conductors . 37. He was a good conductor but turned down the offer both times, preferring to concentrate on the piano. 38. Ionized atoms are very good conductors . 39. Metals are typically also good conductors of heat, but the conduction electrons only contribute partly to this phenomenon. 40. It is an extremely good conductor .
