Here’s a case for saying that objects in the mirror are closer than they appear: The mirror is slightly convex so as to give the driver a wider field of view. As a result, the expanse of mirror reflecting light from the object into my eye is smaller than the expanse would be if the mirror were flat.
Graphite is an electric conductor, consequently, useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
Note on the left that when the carrier wave of FM radio is modulated with sound that the distance between the waves, or the frequency of the carrier wave, changes. Thus, AM radio works by changing the amplitude of the carrier wave and FM radio works by changing the frequency of the carrier wave. Frequency Response.
