Example: The frozen biome was covered in thick white snow. The air was chilled and you could see an arctic fox occasionally.
Meters would be the best way to record the length
Well, we usually assume that the resistance of a circuit component
is constant and doesn't change. But the truth is that for anything
that conducts current, its resistance always increases somewhat
when it warms up.
For things like light bulbs, electric toasters, space heaters, electric
stove burners, the heat coils in a blow-dryer ... anything that's
designed to be really hot when it's doing its job ... the resistance
of those things increases significantly when they come up to their
operating temperatures.
The wavelength would decrease because frequency is inversly proportional to the wavelength provided the speed is constant: f=v/λ
