Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest. Wave Length: The distance between two consecutive wave crests or between two consecutive wave troughs.
What are waves in physics A level?
A wave is just the propagation or storage of energy through a medium or the vacuum, without any transfer of the medium itself. Travelling waves transfer energy from one point to another through a vacuum or a medium. Standing waves do not transfer energy, but instead store energy in the medium or vacuuum.
What is wave in physics PDF?
WAVES, , CHAPTER-15, , WAVES, , Wave: A Wave is a sort of disturbance which transmits energy and momentum in a medium, without transfer of particle., Ex: Sound waves, light waves, waves of water, matter waves etc., Wave motion: The propagation of disturbance from one point to another point is called wave, motion., …
What are the 4 types of waves?
- Radio waves.
- Ultraviolet waves.
What is Huygens principle a level physics?
Huygens’ principle, also called Huygens-Fresnel principle, a statement that all points of a wave front of sound in a transmitting medium or of light in a vacuum or transparent medium may be regarded as new sources of wavelets that expand in every direction at a rate depending on their velocities.
What are amplitude waves?
The amplitude ( ) of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough . Be careful with this quantity – the centre line is not always given in a diagram. Amplitude is measured in metres ( ).
What are the 7 types of ocean waves?
- Spilling waves. Also known as mushy waves in the beach-goers’ terminology, these waves are formed at gentle inclinations of the ocean floor.
- Plunging Waves.
- Surging waves.
- Collapsing waves.
- Tidal waves.
What are four basic properties of waves?
All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
What are 5 wave properties?
- Property 1:Amplitude. The maximum displacement of the wave from the mean position is called the amplitude of the wave.
- Property 2: Frequency.
- Property 3: Wavelength.
- Property 4: Time Period.
- Property 5: Speed.
What are the types of wave motion?
There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.
What is W in wave?
The wavenumber, k, tells us how quickly the wave oscillates in space, while is the frequency, w, tells us how quickly the wave oscillates in time.
What are the difference between transverse and longitudinal waves?
Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
What are the 2 general types of waves?
Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.
What is the top of a wave called?
The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.
Who Discovered wave?
In his Traité de la Lumière (1690; “Treatise on Light”), the Dutch mathematician-astronomer Christiaan Huygens formulated the first detailed wave theory of light, in the context of which he was also able to derive the laws of reflection and refraction.
What is difference between interference and diffraction?
Interference may be defined as waves emerging from two different sources, producing different wavefronts. Diffraction, on the other hand, can be termed as secondary waves that emerge from the different parts of the same wave. The contrast between maxima and minima is very good.
Is light a particle or a wave?
Light can be described both as a wave and as a particle. There are two experiments in particular that have revealed the dual nature of light. When we’re thinking of light as being made of of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy.
What is wavefront and Huygens principle?
Huygens stated that light is a wave propagating through space like ripples in water or sound in air. Hence, light spreads out like a wave in all directions from a source. The locus of points that travelled some distance during a fixed time interval is called a wavefront.
What are the 7 properties of waves?
There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below.
What is a frequency of a wave?
In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Is wavelength a unit?
Units of Wavelength The SI unit of wavelength is meter because the wavelength is a measure of distance. As a measure of speed and distance, one meter is defined as the distance covered by light travelling in a vacuum in a duration of 1/ (3 x 10 8 ) seconds.
Which wave is the biggest?
An earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.
How waves are formed?
Waves occur when the force of the wind blows over surface water, transferring its energy and causing the water to move in a circular motion. The rise and fall of water molecules creates a wave that moves in the direction of the wind.
The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height.
What is the speed of a wave?
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.
