Two sound waves are emitted from identical sources at the same time. They each travel a distance of 10 m, but one wave reaches the destination faster than the other. What can you conclude about the two waves?

One wave is a transverse wave and the other is longitudinal

The waves have different amplitudes

The waves have different wavelengths

The waves are traveling through two different media

Two students are holding opposite ends of a spring in a classroom. One student stands on the left end of the classroom and the other stands at the right end. They shake the spring so that a longitudinal wave travels along the spring. In which directions will the longitudinal wave oscillate?

right and up

left and down

up and down

left and right

Match the following

Stavka koja se može prevući		Odgovarajuća stavka
Interference		occurs when a wave strikes a boundary between two media and bounces back into the medium from which it was originally traveling.
Reflection		occurs when a wave changes speed. This causes the wave to bend, and it typically occurs when wave moves from one medium to another.
Refraction		in terms of transverse waves, it describes the orientation of the oscillations relative to the direction in which the wave propagates.
Diffraction		occurs when two or more waves interact with each other. The new wave is a combination of the original two, with the amplitude equal to the sum of the two waves individual amplitudes.
Resonance		the spreading out of waves when they encounter a barrier or a narrow opening
Polarization		the tendency of an object to vibrate with a greater amplitude at a particular frequency, known as the resonant frequency.

Which statement best compares the movement of P waves and S waves?

Both P and S waves move matter up and down, perpendicular to the direction of the wave

Both P and S waves move matter back and forth, in a direction parallel to the direction of the wave

P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave

P waves move matter up and down, perpendicular to the direction of the wave, while S waves move matter back and forth, in a direction parallel to the direction of the wave.

Why do surface waves arrive last at a seismograph station?

They propagate more slowly than the other seismic waves.

They have less energy than the other seismic waves.

They travel through denser rock than the other seismic waves.

They travel a greater distance than the other seismic waves.

1

Which statement best explains why seismic waves sometimes deflect when they pass from one type of rock to another?

Some minerals absorb seismic waves.

The speed of the waves changes as rock density changes.

Seismic waves cannot pass through some types of solids.

The speed of the waves changes with distance from the epicenter.
