Ari moves a rope's end up and down 6 times in 4 s, making waves of wavelength 0.8 m. How fast do the waves travel?
Bo moves a rope's end up and down 10 times in 8 s, making waves of wavelength 0.6 m. How fast do the waves travel?
A wave crest travels right along a rope. Point P is on the flat rope just ahead of the crest. Which way will P move next, Jun?
- Down
- Right, with the wave
- It will not move
- Up
The crest has just passed point P and moves on to the right. Which way does P move now, Kira?
- Right, with the crest
- Down
- Up
- Left, back toward the start
A cork floats on a water wave moving right. Over one full wave cycle, where does the cork end up, Luz?
- One wavelength to the right
- Half a wavelength to the right
- Back where it started
- One amplitude higher
Light passes through one polarizing filter, but a second filter turned 90° blocks it. What does this show, Milo?
- Light waves vibrate sideways to the direction they travel: they are transverse
- Light waves need a material to travel through, like a rope
- Light waves carry matter along with the energy
- Light waves vibrate along the direction they travel, like sound
S-waves from an earthquake do not pass through Earth's liquid outer core, but P-waves do. What does this suggest about S-waves, Noah?
- They are transverse: a liquid cannot carry a sideways shear
- They are longitudinal, like sound in a liquid
- They are electromagnetic, and liquids block those
- They are faster than P-waves, so they skip the core
