Frequency and amplitude are both terms used to describe characteristics of waves, such as sound waves, light waves, or vibrations. Here's the difference between the two:
1. **Frequency:**
- **Definition:** Frequency refers to the number of complete cycles of a wave that occur in a given unit of time.
- **Unit:** It is measured in Hertz (Hz), where 1 Hz equals one cycle per second.
- **Characteristics:** Higher frequency means more cycles occurring within a specific time period, resulting in a higher pitch in sound waves or shorter wavelengths in light waves.
- **Example:** In sound, high-frequency waves produce high-pitched sounds like a whistle, while low-frequency waves create low-pitched sounds like a bass drum.
2. **Amplitude:**
- **Definition:** Amplitude refers to the maximum extent of displacement or variation in a wave from its mean position. It measures the intensity or strength of a wave.
- **Unit:** It is typically measured in decibels for sound waves and in units like volts or meters for other waves.
- **Characteristics:** Higher amplitude indicates a stronger or louder sound in the case of sound waves. For light waves, it represents the brightness or intensity of the light.
- **Example:** In sound, larger amplitude produces louder sounds, like a loudspeaker compared to a quiet whisper.
In essence, frequency determines how frequently a wave completes a cycle in a given time, while amplitude represents the strength or intensity of that wave.

I'm good
Answer:
I hope it helps :)
Explanation:
Amplitude—distance between the resting position and the maximum displacement of the wave.
Frequency—number of waves passing by a specific point per second.
