Which of the following defines "frequency"?

a property of a wave that describes how many wave patterns or cycles pass by in a period of time

the distance between adjacent peaks in a series of periodic waves

the speed at which electromagnetic radiation travels in a vacuum

l = c/n

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
