What is a 3 way dimmer called?
More ambiguity on the subject of 3 way circuits. Some 3 way dimmer kits refer to the two modules as "master" and "slave". IMHO the main dimmer module should really be called the slave because it takes orders from the other (remote) module.
How many ways to control a light?
The British are most correct. There are two ways to control the light, one way at each switch. We may say three way because there are three ways the switches can be set, Both up, both down, one up, one down. Oddly Wikipedia claims a SPST switch is a two way switch but many of their articles seem to be written by non Americans. For instance try looking up GFCI and you are directed to the European term RCD. Best to just say SPST for a single location switch and no confusion. Note I have heard some here call a single location switch a single pole switch to differentiate it from a 3-way but a 3-way is also a single pole switch. Now back to our regularly scheduled program.
Can a 3 way dimmer work on a single switch?
