Tension is a state of mental or emotional strain caused by stress, uncertainty or conflict. It builds through pressure, expectations or opposing forces. Physical tension tightens muscles and affects the body. Emotional tension creates anxiety and unease. It can arise ...

The Doppler effect is the change in frequency or wavelength of a wave due to the motion of the source or observer. When the source moves toward the observer the frequency increases and the wavelength decreases. When it moves away ...
Frequencies measure how often something happens within a specific period. They are used in physics, engineering, music, and communication. In sound, they determine pitch. In radio, they help transmit signals. Higher frequencies mean shorter wavelengths. Lower frequencies travel farther. Measured ...
A traveling wave is a disturbance that moves through a medium or space, transferring energy without transporting matter. It can be mechanical or electromagnetic and propagates with a specific speed, frequency, and wavelength. Examples include water waves, sound waves, and ...
The speed of sound depends on the medium through which it travels. In dry air at 20°C it is about 343 meters per second. It moves faster in solids and liquids than in gases because particles are closer together. Temperature ...
Frequency refers to how often something occurs within a given time frame. It is commonly used in physics to measure wave cycles per second in hertz. In everyday life it describes repeated actions like daily routines and habits. High frequency ...
A longitudinal wave moves in the direction of energy transfer through compressions and rarefactions. Sound waves in air and seismic P-waves in Earth are examples. Particles oscillate parallel to wave motion. These waves require a medium like air, water, or ...
Wave velocity is the speed at which a wave propagates through a medium. It depends on the wave type and the properties of the medium. It is given by the formula velocity equals frequency multiplied by wavelength. Different waves like ...
A mechanical wave is a disturbance that travels through a medium, transferring energy from one point to another. It requires a medium like solid, liquid or gas to propagate. Examples include sound waves, water waves and seismic waves. Mechanical waves ...
Acceleration is the rate of change of velocity of an object with respect to time. It is a vector quantity measured in meters per second squared. Acceleration can be uniform or non-uniform and positive or negative. It occurs due to ...
