-- Equations #2 and #6 are both the same equation,
and are both correct.
-- If you divide each side by 'wavelength', you get Equation #4,
which is also correct.
-- If you divide each side by 'frequency', you get Equation #3,
which is also correct.
With some work, you can rearrange this one and use it to calculate
frequency.
Summary:
-- Equations #2, #3, #4, and #6 are all correct statements,
and can be used to find frequency.
-- Equations #1 and #5 are incorrect statements.
::Answer::
The answer you're looking for is Electrical Energy.
because water is loosely packed but when it is cold it becomes closely packed in order to form ice and thus the force attraction between them also increase.
The product of (voltage) times (current, in Amperes) is POWER.
