Define amplitude, frequency, period, wavelength, and velocity of a wave; Relate wave frequency, period, wavelength, and velocity; Solve problems involving wave properties
A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time. A wave with a larger frequency has more energy. If a wave’s frequency doubles, its energy also doubles. A wave’s energy is proportional to the square of its amplitude.
In general, the energy of a mechanical wave and the power are proportional to the amplitude squared and to the angular frequency squared (and therefore the frequency squared). Another important characteristic of waves is the intensity of the waves.
Energy and Momentum. Electromagnetic waves have energy and momentum that are both associated with their wavelength and frequency.
Just as we saw in our discussion of mechanical waves, the wave energy has to move through something. In the case of electromagnetic waves, the energy moves through space, and space has certain properties that determine how electric and magnetic fields behave. We've seen that the wave speed in space or on Earth is 3 x 10 8 meters per second ...
Properties of waves. Types of waves. Waves are one of the ways in which energy may be transferred between stores. All waves transfer energy but they do not transfer. matter. . Waves can be...
Demonstrate understanding of wave properties such as wavelength, amplitude, frequency, period, and speed and mathematically relate these properties to one another. Apply the relationship among wave speed, frequency, and wavelength to solve problems.
