It depends on the related laws of the state in which the property is located, as to whether someone can even cross your property to access their landlocked property, but I have never heard of a landowner being required by law to maintain the condition of anothers access. For example, Louisiana has a very old law [Napoleanonic Code, I think] which allows one to cross anothers property to access their own landlocked property. However, they are not allowed to cut any trees, or to install culverts or bridges, or to improve the "wagon track" in any way, including the addition of gravel, logs, or other "fillers" to the mudholes. Additonally, the landowner has no responsibility to provide any maintainence.
The property you are referring to is called wavelength. It is the distance between the same point on two consecutive waves, such as from one crest to the next crest or from one trough to the next trough.
Trough
The property of light defined by the distance between identical points on adjacent waves is called wavelength. Wavelength is typically measured from peak to peak or trough to trough of a wave. It determines the color of light and is inversely related to the frequency of the wave.
A very old trough. A hard-wearing trough. A durable trough. One tough trough.
Means that someone is telling a poor lie which is easily noticeable.

The pig ate from the trough. Trough is a noun.
The possessive form of the singular noun trough is trough's.
That distance is a definition, not a wave property. It's defined as the "wavelength".
A trough, or a drinking trough.
