Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. Amplitude is the maximum distance the particles of the medium move from their resting positions when a wave passes through.
A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance.
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
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.
A wave is a periodic disturbance that moves away from a source and carries energy with it.

A wave is a periodic, continuous disturbance that consists of a train or succession of pulses.
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength.
Wave amplitude is determined by the energy of the disturbance that causes the wave. A wave caused by a disturbance with more energy has greater amplitude.
Reflection occurs when waves bounce back from a surface they cannot pass through. … When waves strike an obstacle head on, the reflected waves bounce straight back in the direction they came from. When waves strike an obstacle at any other angle, they bounce back at the same angle but in a different direction.
Diffraction also occurs when a wave passes through a gap (or slit) in a barrier. … When the gap size is smaller than the wavelength (top movie), more diffraction occurs and the waves spread out greatly – the wavefronts are almost semicircular.
The answer is “a hammer hitting a metal cup”. Sound waves are formed when a vibrating object makes the encompassing medium vibrate. A medium is a material in which a wave goes through.
A single disturbance passing through a medium is called a pulse. When the disturbances are repeated in a periodic manner, the pulses generate a continuous wave. Longitudinal waves (also called compression waves – a slinky pushed and pulled) – moves parallel (same direction) to the wave motion.
|Transverse wave||Oscillations where particles are displaced perpendicular to the wave direction.|
|Longitudinal wave||Oscillations where particles are displaced parallel to the wave direction.|
The density of the medium is among the factors which affect the speed of sound. The higher the density, the faster the sound travels through the medium. And, on the other hand, the lower the density, the slower is the speed of propagation of sound.
Investigation : Observation of Pulses
Flick the rope at one end only once. What happens to the disturbance that you created in the rope? … A pulse is a single disturbance that moves through a medium. In a transverse pulse the displacement of the medium is perpendicular to the direction of motion of the pulse.
A transverse wave has a disturbance perpendicular to its direction of propagation, whereas a longitudinal wave has a disturbance parallel to its direction of propagation.
The amount of energy in a wave depends on its height and wavelength as well as the distance over which it breaks. Given equal wavelengths, a wave with greater amplitude will release more energy when it falls back to sea level than a wave of lesser amplitude.
Waves are dependent on three major factors – wind speed, wind time and wind distance.
The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
Examples of disturbances that cause primary succession include retreating glaciers, volcanic eruption and the erosion of sand dunes. Human activity can also be a cause of primary succession, such as the creation of a paved surface. These types of disturbances leave bare rock exposed or otherwise accessible.
Disturbance Affects Species Diversity. (A) Species diversity is low at low disturbance frequency because of competitive exclusion. … At high disturbance frequency, species diversity is predicted to be low, because only “weedy” species that quickly colonize and reach maturity are able to survive.
The wavelength of a matter wave associated with a particle is inversely proportional to the magnitude of the particle’s linear momentum. The speed of the matter wave is the speed of the particle.
