Frequency.
The number of wave crests passing a given place in one second is the frequency of the wave given in cycles per second, or Hertz.
Hertz.
That's called the frequency.

a watt is power, or 1 joules sec= 1 watt an amp is 6.242 × 1018 electrons passing a given point each second,
The number of electrons in any given shell can be represented by 2n2, where n = the shell number. The first shell has 2, second has 8, third has 18...
When measuring current, we are measuring the number of electrons (conventionally positive charges) passing through the cross section of the conductor in one second.AnswerActually, the unit of electric current, the ampere, is defined in terms of the force between two parallel current-carrying conductors, and NOT in terms of the quantity of electrons passing a given point!
hertz
That is frequency.
Wave speed
The number of protons and electrons in a neutral atom are the same and given by the element's atomic number.
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
