Math Problem Statement

Identify the frequency, wavelength, and amplitude in the diagram below using the letters included. Explain how frequency, wavelength, and amplitude affect each other.

Solution

In the given wave diagram, we can identify the following quantities:

  1. Wavelength (A): The distance between two consecutive identical points on the wave, such as from peak to peak or trough to trough. In the diagram, the labeled segment "A" represents one full wavelength.

  2. Amplitude (C): The height of the wave from the equilibrium (centerline) to the crest (peak) or to the trough. The labeled segment "C" shows the amplitude of the wave.

  3. Frequency: The number of waves passing a point in one second. Since the diagram shows two full waves (two cycles) occurring within one second, the frequency is 2 Hz (hertz), meaning 2 waves per second.

Relationship between Frequency, Wavelength, and Amplitude:

  • Frequency and Wavelength are inversely related. As the frequency increases, the wavelength decreases, and vice versa. The wave's speed remains constant for a given medium.
  • Amplitude is independent of frequency and wavelength. It measures the energy or intensity of the wave, but it does not affect the frequency or wavelength. Larger amplitude means more energy.

Here are 5 relative questions to explore:

  1. How is the speed of a wave related to frequency and wavelength?
  2. What unit is used to measure amplitude?
  3. How do amplitude and energy relate to each other?
  4. What happens to the wave when the frequency doubles but the wave speed remains constant?
  5. Can a wave have the same amplitude but different frequencies?

Tip: Frequency is a key factor in determining pitch in sound waves or color in light waves.
