A medium and a pressure differential
MY hairdresser told me that retouches need to occur every 3 months
For refraction to occur in a wave, the wave must enter a new medium at an angle.
A standing wave can occur only at specific frequencies that are called natural frequencies.
The period of a wave is the time it takes for one complete cycle of the wave to occur, usually measured in seconds. It is the reciprocal of the frequency of the wave, which is the number of cycles that occur in one second.
The number of waves that occur in a given time period depends on the frequency of the wave. The frequency is defined as the number of complete wave cycles that occur in one second and is measured in hertz. For example, if a wave has a frequency of 10 Hz, it means that 10 complete wave cycles occur in one second.
The amplitude of a wave does not affect its period. The period of a wave is determined by its frequency, which is the number of complete cycles of the wave that occur in a given time period. The amplitude of a wave, on the other hand, is the maximum displacement of the wave from its equilibrium position. Changing the amplitude of a wave will not change the time it takes for one complete cycle of the wave to occur.
The time it takes for a complete cycle or wave oscillation to occur is called the period. It is usually measured in seconds and is inversely proportional to the frequency of the wave.
amplitude Longitudinal waves occurs when the motion of the medium. This is parallel to the direction of the wave.
A tsunami is an ocean wave that is caused by an earthquake. It would occur after an earthquake.
The period of a wave is measured in seconds by calculating the time it takes for one complete cycle of the wave to occur.
In a transverse wave, the motion of the wave is perpendicular to the direction in which the energy is moving. This means that the oscillations of the particles in the wave occur perpendicular to the direction in which the wave is traveling.
