- Waves are a fundamental concept in physics and have several properties that describe their behavior. Here are some key properties of waves:
Amplitude: The amplitude of a wave refers to the maximum displacement of a particle in the medium from its equilibrium position. In simpler terms, it measures the intensity or strength of the wave. For example, in a transverse wave like a water wave, the amplitude represents the height of the wave crest or depth of the wave trough.
Wavelength: The wavelength of a wave is the distance between two consecutive points that are in phase with each other. It is often denoted by the symbol λ (lambda) and is usually measured in meters. In a transverse wave, such as light or electromagnetic waves, the wavelength corresponds to the distance between two consecutive wave crests or troughs.
Frequency: The frequency of a wave is the number of complete cycles or oscillations it completes in one second. It is measured in hertz (Hz), where 1 Hz equals one cycle per second. The frequency is inversely proportional to the wavelength, meaning that waves with longer wavelengths have lower frequencies and vice versa.
Period: The period of a wave is the time it takes for one complete cycle or oscillation to occur. It is the reciprocal of the frequency and is measured in seconds per cycle. Mathematically, period (T) is related to frequency (f) by the equation T = 1/f.
Speed: The speed of a wave represents how fast the wave is propagating through a medium. It is calculated by dividing the distance traveled by the wave by the time it takes to travel that distance. The speed of a wave depends on the properties of the medium through which it is traveling. For example, in a vacuum, electromagnetic waves (such as light) travel at a constant speed known as the speed of light (approximately 3 x 10^8 meters per second).
Phase: The phase of a wave describes the position of a particle in its oscillatory motion relative to a reference point. It is often represented in terms of angles or fractions of a cycle. Waves that are in phase have their crests and troughs aligned, while waves that are out of phase have a phase difference between them.
Reflection: Reflection occurs when a wave encounters a boundary or obstacle and bounces back. The angle of incidence (the angle between the incident wave and the normal to the boundary) is equal to the angle of reflection (the angle between the reflected wave and the normal). Reflection plays a crucial role in phenomena such as echoes and the way we perceive light.
Refraction: Refraction happens when a wave passes from one medium to another and changes its direction due to a change in its speed. This change in direction occurs because the wave's speed is different in different media. Refraction is responsible for various phenomena, including the bending of light when it passes through a prism or the way a straw appears broken when immersed in water.
These are some of the essential properties of waves. Waves can exhibit different behaviors and characteristics depending on their type (e.g., mechanical waves, electromagnetic waves) and the medium through which they propagate.

Waste of time useless
Thanks
I think you are useless😂
As we know....
Ba adab Ba naseeb
Bay adab bay naseeb
Yy ap jese logo hi k liyy h❤

May Allah give you success Amen
sir please reflection ,refraction and diffraction ki defination btaa do
Very very good lectures
Thanks dear student may Allah give you success Ameen 🍀
sir please reflection ,refraction and diffraction ki defination btaa do
I advise you Try to write it in your own words
But still here is the definition
Reflection
The bouncing back of waves when they encounter a boundary or obstacle.
Refraction:
The change in direction of waves as they pass from one medium to another with different wave speeds.
Deflection:
The change in the path of waves as they encounter an obstacle or slit, leading to spreading or bending of the wavefront.

@@BACKBENCHERSACADEMY-tg3ep Ameen sir pls pray for my 9th upcoming result to ger 530+
InshAllah 👍🏼

sir diffraction ki condition bta dein please
When waves hit an obstacle, they bend around it if the obstacle size is similar to the wavelength.
confidently teacher in our pakistan amazing😮😮
Thanks 🤗
sir may from sindh text book say hun kia aap wo hi book prhaa teen hien ??😊
Ye national book hai but Topics same hai don't worry. jab ma bh matric me tah to mujhe bh yaheh dar laga rahta tah k Kon se key book se karon bad me pata Chala k topics same hai ap jis Marzi book se karo har book me wo topic k meaning same hai just Exercise k kch questions change hote hen wo bh agr Concept clear ho to ho jate hen Concept pe focus karo aur khud se likhne ki kosish karo
thanks sir kia aap chemistery nahi prhaa teen
In future filhal nhi
Outstanding ❤
Thanks 😊
Zabardast sir JazakAllah
😀🤗
Amazing lecture 🔥
Thanks a lot you appreciation motivates us
Mza agya video dhek k
Thanks dear student
Thanks sir
Welcome 😊
Ap ky parhany ka style boht best hai💜
Thanks dear student 🙂
good
Thanks dear student
Very good sir gggggg
Thanks dear student may Allah give you success Ameen 🍀
Ameen
😮ufff sir goooddddd❤
Thanks dear student 😊
❤❤❤❤❤
🤗
amazing
Thanks dear student
❤❤❤
Thanks dear student
Bad lecture 😭
Yess
It's better to study yourself than don't waste your time in watching such amazing lectures cuz probably you don't have any brain to process what he's saying cuz I understood every single word.
@@Minahil589go find someone else than u don't deserve these type of lectures 😂
May Allah give you success Amen 🍀
