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 ...
