- The top-left wave has a higher frequency (more waves per second) than the bottom-left wave.
- The top-right wave has a greater amplitude (height of each wave) than the bottom-right wave.
- Frequency is determined by counting the number of complete wave cycles within a given time frame; more cycles mean higher frequency.
- Amplitude is measured from the center line to the peak (or trough) of the wave; a taller wave means greater amplitude.
- The top-left and top-right waves represent a sound that is higher-pitched and louder, respectively, compared to the bottom waves.
Parent Tip: Review the logic above to help your child master the concept of sound waves worksheet.
