The relationship between frequency, wavelength, and wave speed can be understood using a simple formula:
Wave Speed = Frequency × Wavelength
This means:
Waves move differently depending on the material they travel through. Different materials are called mediums. Each medium has its own qualities, like how dense or stretchy it is, which affects how fast waves can move.
In general:
For example, sound travels quickly in metals because the particles are packed closely together. But in the air, sound moves much slower. This shows us how the medium affects how waves behave.
When a wave moves from one medium to another, the frequency stays the same. This is because the frequency depends on where the wave comes from.
However, the wavelength changes when the wave speed changes in a new medium.
Let’s consider sound traveling from air to water:
To explain this with numbers:
Now, when the sound travels to water, where the speed is around 1482 meters per second, we can find the new wavelength:
Wavelength in Water (λ_water) = Speed in Water (v_water) ÷ Frequency (f)
This shows that when the space the wave is in changes, the wavelength also changes while the frequency stays the same.
To wrap it up, waves act differently in different materials. The way frequency, wavelength, and wave speed are connected is clear through the wave formula. This shows us just how flexible and interesting waves are in different situations.
