(NO LINKS!) Which statement best describes what happens when oil and water are stirred together?

A. Water and oil molecules have opposite electrical charges, causing them to repel each other other and seperate.
B. Water molecules will attract each other electrically, but they will not attract oil molecules, causing seperation.
C. Oil and water molecules have like charges, causing them to repel each other and seperate.
D. Oil molecules will repel each other electrically, leading to complete mixing of the two substances.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
