Understanding Wave Frequency, Speed, and Wavelength Relationships

Waves have higher frequencies with shorter wavelengths, but wave speed remains constant across different frequencies.

### Understanding Wave Frequency, Speed, and Wavelength
* 🔄 **Frequency**: The rate at which something occurs, measured in cycles per second (**hertz**). One hertz is one cycle per second, with higher frequencies meaning **more cycles per second**.
* 🏃 **Wave Speed**: Determined by the medium, not the frequency. Waves of different frequencies travel at the **same speed** in the same medium.
* 📏 **Wavelength**: The distance between two corresponding points on a wave, such as crest to crest. Inversely related to frequency: **higher frequency waves have shorter wavelengths**.
* 🔁 **Frequency (f)** is equal to **speed (v)** divided by **wavelength (λ)**, or **f = v/λ**.
* 🛣 **Shorter cars (higher frequency waves)** pass through a toll plaza more frequently than **longer cars (lower frequency waves)** moving at the same speed.
* 🧮 **Formula Adjustment**: While f = v/λ, it's more accurate to say that **wavelength is the result of wave speed divided by frequency**.
* 🚀 **Changing wave speed** does not affect frequency, only wavelength. Frequency is solely determined by the **source of the wave**.
* 📝 **Practice Problems**: Provided to test understanding of **frequency, speed, and wavelength relationships**.

Frequency is the rate at which cycles occur, measured in cycles per second or hertz.

One hertz equals one cycle per second, and both full and partial waves can contribute to the frequency.

The number of waves divided by the number of seconds determines the wave frequency in hertz.

Wave frequency is determined by the number of cycles per second, measured in hertz.

The source of the waves plays a crucial role in determining the frequency, with a faster source movement resulting in more waves per second.

However, wave speed remains constant regardless of frequency, as waves traveling through the same material move at the same speed.

Wave speed is determined by the medium, not the source, and does not change with frequency.

When wave speed changes, the wavelength adjusts proportionally, while the frequency remains constant.

The relationship between frequency and wavelength can be illustrated with an analogy of cars, where shorter wavelengths are like short cars and longer wavelengths like longer cars, both moving at the same speed.

The Relationship Between Wave Frequency and Wavelength

Higher frequency waves are shorter and pass by more often, while lower frequency waves are longer and less frequent.

The speed of the waves is constant, so a change in speed requires a change in wavelength to maintain the same number of waves passing by per second.

The formula for wavelength is derived from the wave's velocity divided by its frequency, emphasizing the importance of the wave source in determining its frequency.
