Question
Which property of a wave is related to its
frequency?Solution
The energy of a wave is directly proportional to its frequency. The higher the frequency, the higher the energy. This is true for electromagnetic waves such as light. Energy E is given by the formula E = h × f, where h is Planck's constant and f is frequency.
