Transmission
What is Transmission?
- When an object is transparent and when waves of vibrations are going through the transparent object it vibrates through the atoms next to each other and through the object and is shown on the other side of the object
- Describes the transmission of mechanical energy through vibrations
Transmission form Low Density to High Density
- Low density will have a faster wave speed, while high density will have a slower wave speed
- The wave for the low density will be reflected and inverted when changed to a high density
- The amplitude of the wave will get from bigger to small when the wave goes through low density to high density
- A wave first travels regularly
- When transmitted, the density increases and it travels slowly in the reflected region
- Also, the difference of the two waves gets a wave of its own value, that wave is inverted into the opposite direction
Transmission form High Density to Low Density
- High density will have a slower wave speed, while low density will have a faster wave speed
- The wave for the high density will be reflected when changed to a slow density
- The amplitude of the wave will get from small to big when the wave goes through high density to low density
- A wave first travels regularly
- When transmitted, the density increases, and it travels faster in the opposite region
- Also, the value gained of the wave gets a wave of its own, the wave goes in the opposite direction
Examples
- Wave starts as normal
- When transmitted it becomes slower
- The difference of the two is reflected back
- Opposite direction & opposite amplitude
- Thus, it's low to high density
- Wave starts as normal
- When transmitted it becomes faster
- The value gained of the wave gets a wave of it own
- Opposite direction
- Thus, it's high to low density
