How can you tell which has the greater amount of energy when two longitudinal waves are traveling through the same medium?
Depends on distance between compressions and rarefactions. When comparing two longitudinal waves that are traveling through the same medium, how can you tell which has the greater amount of energy? The distance from one point on a certain to wave to the same point on the following wave.
What is the direction of energy in a longitudinal wave?
With sound waves, the energy travels along in the same direction as the particles vibrate. This type of wave is known as a longitudinal wave , so named because the energy travels along the direction of vibration of the particles.
What happens to the waves as you increase or decrease the frequency?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
What type of waves carry energy at a right angle to the direction of energy flow?
A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer.
How are waves involved in energy transfer?
Energy is transferred in waves through the vibration of particles, but the particles themselves move in a perpendicular fashion to the horizontal movement of the wave. Energy is transformed between potential (stored) and kinetic (movement) energy as the particles go from rest to movement and back to rest.
Do electromagnetic waves carry energy?
An electromagnetic wave, although it carries no mass, does carry energy. It also has momentum, and can exert pressure (known as radiation pressure). The energy carried by an electromagnetic wave is proportional to the frequency of the wave.
When a wave moves what happens to the medium?
Q: How do the particles of the medium move when a wave passes through them? A: The particles of the medium just vibrate in place. As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on.
