what causes a disturbance that results in a wave

A wave is a periodic disturbance that spreads out from a source and carries energy with it. There are two types of waves mechanical and electromagnetic.

What happens when waves pass by?

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.

Is a single disturbance while?

A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance.

Is a wave where the disturbance travels in the same direction as the wave?

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.

Why does energy move in 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.

What refers to a periodic disturbance that moves away?

A wave is a periodic disturbance that moves away from a source and carries energy with it.

Which of the following is the succession of periodic disturbance?

Waves in a pool

A wave is a periodic, continuous disturbance that consists of a train or succession of pulses.

How does wavelength affects the frequency of the wave?

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.

Is determined by the energy of the disturbance that causes the wave?

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.

What occurs when waves hit an obstacle straight on?

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.

What happens when a wave passes around a barrier that is shorter than its wavelength?

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.

Which of these most likely cause a sound wave?

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.

What is single disturbance?

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.

Which of the following waves does the disturbance move in a particular direction to the wave?

Key terms

Term Meaning
Transverse wave Oscillations where particles are displaced perpendicular to the wave direction.
Longitudinal wave Oscillations where particles are displaced parallel to the wave direction.

What is the main factor which affects the speed of a sound wave?

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.

Have a single disturbance in one end of the rope what is formed?

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.

In which direction is the wave traveling compared to the disturbance water drops perpendicular or parallel?

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.

What causes a wave?

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. … The gravitational pull of the sun and moon on the earth also causes waves.

What causes electromagnetic radiation?

EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.

How do waves affect the flow of energy?

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.

What are 3 causes of waves?

Waves are dependent on three major factors – wind speed, wind time and wind distance.

What determines the wavelength of a wave?

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.

What is a period in a wave?

Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds. Fetch: The uninterrupted area or distance over which the wind blows (in the same direction).

What is a disturbance in an ecosystem?

ecological disturbance, an event or force, of nonbiological or biological origin, that brings about mortality to organisms and changes in their spatial patterning in the ecosystems they inhabit.

What caused the disturbance of the ecosystem in this example of primary succession?

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.

How does disturbance affect biodiversity?

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.

What are the affecting factors for the wavelength of a moving particle?

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.

How is wavelength affected?
