Pesticide Treadmill. Definition - What does Pesticide Treadmill mean? The term pesticide treadmill describes the phenomenon whereby pesticide use prevents any natural form of control from taking place, thereby resulting in the need for repeated, routine applications of pesticide. The pesticide treadmill is said to escalate when the control of one pest provides a window of opportunity for other pests and the need for further chemicals.
Before hitting some types of waves, let me describe the common characteristics of electromagnetic waves. Electromagnetic waves are a type of transverse waves. These waves do not require a medium to travel. As the name of the waves imply, these waves show electrical and magnetic properties.
Electromagnetic waves are formed by the vibrations of electric and magnetic fields. These fields are perpendicular to one another in the direction the wave is traveling. Once formed, this energy travels at the speed of light until further interaction with matter.hese changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
