when waves are closer together and there are more waves, then the wave has a higher _______. (2 points)
amplitude
frequency
wavelength

Explanation:

First Question (Which wave has the highest frequency?)

Step1: Recall frequency definition

Frequency is the number of wave cycles (crests/troughs) per unit length (or time). More cycles in the same length mean higher frequency.

Step2: Compare wave cycles

• Wave A (red): Fewer cycles.
• Wave B (orange): Fewer than C, D, E.
• Wave C (green): Fewer than D, E.
• Wave D (blue): Fewer than E.
• Wave E (purple): Most cycles (closest together, most waves).

Amplitude is height, wavelength is distance between cycles, frequency is cycles per unit. Closer waves (more cycles) mean higher frequency.

Answer:

E. Wave E (purple)

Second Question (When waves are closer... higher ______)
