How does the amount of energy transferred by a wave relate to wavelength?
For water waves, those with a high speed and long wavelength (like a tsunami) have the most energy. For electromagnetic waves, speed is constant, so waves with a high frequency and a short wavelength (like X-rays) are the most energetic. For all waves, a greater amplitude means more energy.
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.
How does the intensity of or energy carried by a wave change with distance as the wave moves further away from the source of the wave?
As the wave moves out from a source, the energy is conserved, but the intensity decreases as the area increases.
What is the relationship between the frequency of a wave?
What is the relationship between the frequency of a wave and the amount of energy the wave carries? The greater the energy,the larger the frequency&the shorter (smaller) the wavelength.
This illustrates the relationship between energy and the amplitude of a wave. The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude.
Why do some waves have more energy than others?
Measuring the energy in a wave. Why do some waves have more energy than others? A wave’s frequency and wavelength are both indicators of its energy, but this differs for different types for waves. For water waves, those with a high speed and long wavelength (like a tsunami) have the most energy.
How are energy and information transferred by waves?
In other words, the people move vertically in their seats while the wave moves horizontally around the stadium. This is because waves transfer energy and not mass.
