What causes particles in matter to move back and forth along the same direction?
A transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels.
What type of wave causes particles in matter to move back and forth along the same direction in which the wave travels?
Mechanical wave that causes particles in matter to move at right angles to the direction the wave travels. Mechanical wave that causes particles in matter to move back and forth along the direction the wave travels. Distance between one point on a wave and the nearest point moving with the same speed and direction.
What is a wave that can travel only through matter?
A wave that can travel only through matter is called a mechanical wave. Mechanical waves travel through solids, liquids, and gases. Mechanical waves cannot travel through a vacuum. A material in which a wave travels is called a medium.
What is the number of wavelengths that pass a given point second?
Chapter 10 – Waves
| A | B |
|---|---|
| frequency | the number of wavelengths that pass a fixed point each second |
| period | the amount of time it takes one wavelength to pass a point |
| amplitude | a measure of the energy carried by a wave |
| refraction | the bending of a wave caused by a change in its speed as it moves from one medium to another |
Which is the second type of mechanical wave?
A second type of mechanical wave is called a compressional wave. This type of wave causes particles in matter to move back and forth along the same direction the wave travels. You can think of a compressional wave as a slinky going back and forth. The areas that are squeezed together are called compressions.
What are the crests and troughs of a transverse wave?
Transverse waves are mechanical waves that can have, but do not need, a medium. It causes particles in matter to move move back and forth at right angles to the direction it travels. These waves have high and low points, called crests and troughs. This series of crests and troughs makes the transverse wave you see in the image below.
How is the amplitude of a transverse wave determined?
In a transverse wave, the amplitude is half the distance between the crest and trough. In a compressional wave, the amplitude depends on the density of the material and the length of compressions and rarefactions. A wave with a higher amplitude has more compressed compressions and more spread out rarefactions.
Why is the amplitude of a compressional wave higher?
In a compressional wave, the amplitude depends on the density of the material and the length of compressions and rarefactions. A wave with a higher amplitude has more compressed compressions and more spread out rarefactions. In sound waves a higher amplitude means a louder sound.
