Question

using the waves shown, identify the wave with the lowest energy. * q (0.5 points)

Explanation:

Step1: Recall energy - frequency relation

The energy of a wave is directly proportional to its frequency ($E = hf$, where $E$ is energy, $h$ is Planck's constant and $f$ is frequency). Lower - frequency waves have lower energy.

Step2: Identify wave with lowest frequency

The frequency of a wave is the number of complete cycles per unit time. Visually, the wave with the fewest cycles in a given time interval has the lowest frequency. Wave D has the fewest number of cycles compared to A, B and C.

Answer:

D.
