Final answer:
A wiggle in both space and time is a wave, and properties like frequency and amplitude are tied to the wave model of light. Electromagnetic waves are made up of electric and magnetic fields, and the conservation of momentum or kinetic energy depends on specific conditions.
Step-by-step explanation:
A wiggle in both space and time is best described as a wave. Waves are disturbances that transfer energy through space and time, often without the permanent movement of matter. In the context of physics and the wave-particle duality of light, terms like frequency, amplitude, and period are specifically tied to the wave model of light. These properties help to describe the characteristics of waves, whether they are light waves, sound waves, or other types of waves. For example, a tuning fork, a violin string, and a loudspeaker are producing sounds because they are all in a state of vibration, which creates sound waves. In the case of electromagnetic waves, they are composed of both an electric field and a magnetic field. Finally, in classical physics, when discussing conservation laws, more information is typically needed to determine whether momentum or kinetic energy is conserved in a given scenario.
