Question

label the waves.
image of two waves, one blue (higher frequency) and one red (lower frequency), with dashed boxes for labeling, and options: high energy, low energy

Explanation:

Step1: Recall wave energy relation

Wave energy ∝ frequency (E = hf, h=Planck’s constant). Higher frequency = more energy.

Step2: Compare wave frequencies

Blue wave has more cycles (higher frequency) than red wave.

Step3: Assign energy labels

Blue wave = high energy; red wave = low energy.

Answer:

Blue wave: high energy; Red wave: low energy
