When the physics teacher shook the slinky up and down faster,

speed stayed the same; frequency and wavelength both changed

frequency stayed the same; speed and wavelength both change

wavelength stayed the same; speed and frequency both change

Which of the following best describes a longitudinal wave?

The medium vibrates parallel to the direction the wave travels.

The medium vibrates perpendicular to the direction the wave travels.

As a wave moves from one medium to another,

frequency stays the same; speed and wavelength both change

wavelength stays the same; speed and frequency both change

speed stays the same; frequency and wavelength both change

can travel through solids and fluids.

can only travel through solids.

Sound is an example of a _________

Nonsense, sound isn't a wave at all

S-waves do not travel through the outer core. Which of the following is the accurate conclusion that scientists can draw from this information?

Because s-waves are transverse and cannot travel through fluids , the outer core must be fluid .

Because s-waves are longitudinal and cannot travel through fluids , the outer core must be fluid .

Because s-waves are transverse and cannot travel through solids , the outer core must be solid .

Because s-waves are longitudinal and cannot travel through solids , the outer core must be solid .

As seismic waves travel through the inside of the Earth, scientists find that the speed of the S & P waves change. This shows that:

the materials within the Earth have different properties.

the materials within the Earth have all of the same properties.

the entire inside of the Earth is liquid.

the entire inside of the Earth is solid.

Which of the following statements accurately compare "Sound A" and "Sound B" in this picture?

"Sound A" is lower pitch than "Sound B", because "Sound A" has a lower frequency.

"Sound A" has a higher pitch as "Sound B", because "Sound A" has a higher frequency.

"Sound A" has a lower pitch than "Sound B" because "Sound A" has a higher frequency.

"Sound A" has a higher pitch as "Sound B", because "Sound A" has a higher frequency.

Imagine scientists are studying a new planet that experiences frequent earthquakes. Seismographs have been placed all over the planet. The seismographs at most of the stations record only P-waves. What can the scientists infer about the inside of the planet?

The inside of the planet is mostly made up of fluids.

The inside of the planet is mostly made up of solids.

That the planet is made up of tectonic plates.

That there's a magnetic field around the planet.
