Energy E and Frequency n Relationships- Energy is directly proportional to frequencyTo calculate energy from frequency or vice Versa use the following equation. T period the time required for one cycle. Frequency is the number of events per unit of time where an event is repeating at regularly spaced time intervals.
The higher the frequency the shorter the wavelength.
Frequency is the number of events per unit of time where an event is repeating at regularly spaced time intervals. However the equation below is usually the one you see in a chemistry class. Hertz and per second are identical units ie. Frequency the number of waves that pass a fixed point in unit time.
