Characteristics of Mechanical Waves Quiz

Mechanical waves require a medium to propagate and cannot travel through a vacuum.

In a transverse wave, particles in the medium vibrate perpendicular to the direction of the wave's motion.

Mechanical waves can travel through any medium, including solids, liquids, and gases.

Frequency is measured in Hertz (Hz), which represents the number of cycles per second.

Wavelength is the distance between two consecutive crests or troughs of a wave.

The pitch of a sound wave is determined by its frequency, with higher frequencies corresponding to higher pitches.

Sound waves are examples of longitudinal waves where particles in the medium vibrate parallel to the direction of wave motion.

The speed of a wave is determined by the properties of the medium through which it travels, such as density and elasticity.

The speed of a wave is calculated by multiplying the wavelength of the wave by its frequency.

The frequency of a wave is affected by the tension in the medium and the linear density of the medium.

The speed of sound in air increases with increasing temperature.

Amplitude is the maximum displacement of a particle from its equilibrium position in a wave.

In a transverse wave, the direction of particle vibration is perpendicular to the direction of wave propagation.

Sound waves travel faster in denser materials like steel compared to less dense materials like air.

Interference occurs when two or more waves combine to form a new wave with a different amplitude.

Mechanical waves require a medium to propagate, unlike electromagnetic waves, which can travel through a vacuum.
