Mechanical Waves Quiz

It can travel through vacuum due to electric and magnetic fields oscillating perpendicular to each other.

This is the typical speed of sound in air at 20°C (68°F).

One Hertz (Hz) equals one cycle per second.

Particles in this wave move perpendicular to the direction of the wave.

Steel transmits sound well due to its high density and stiffness.

It occurs when waves spread out after passing through an aperture or around an obstacle.

Sound waves need a medium (such as air, water, or solids) to travel.

Frequency and wavelength are inversely proportional; as one increases, the other decreases.

Higher amplitude waves carry more energy.

Speed equals wavelength multiplied by frequency.

Higher frequency waves have higher pitch, perceived as 'high' sounds.

This occurs when waves combine, either constructively (adding amplitudes) or destructively (canceling out).

Wavelength and frequency are inversely proportional; if one increases, the other decreases, but their product (speed) remains constant.

It happens due to the change in speed when transitioning from one medium to another, causing bending.

Wavelength is measured in distance units such as meters.

These waves travel through the Earth's interior and cause the shaking felt during earthquakes.

The motion of the rope occurs perpendicular to the direction of the wave's propagation.

Waves spread out when encountering obstacles or passing through narrow openings.

It requires a medium (water) to travel, and the wave results from a disturbance in that medium.

It states that the angle of incidence equals the angle of reflection.

It represents how fast the wave is propagating through the medium.

Greater amplitude corresponds to louder sounds.

This equation states that the speed of a wave equals its frequency multiplied by its wavelength.

Frequency measures how many complete cycles occur per unit time (usually per second).
