A wave travels right along a rope. A bit of yarn tied to the rope moves up and down as the wave passes. What type of wave is shown?
A student pushes and pulls one end of a slinky so the coils move back and forth in the same direction the disturbance travels. What type of wave is modeled?
A water wave moves across a pan, and a floating cork mostly bobs up and down while the wave travels sideways. What wave type does the cork's motion show?
A sound wave moves from a drum through air. Nearby air molecules vibrate forward and backward along the same line the sound travels. What wave type is this?
A stadium crowd wave moves around the arena while each person mainly stands up and sits down. Which wave type best matches this motion?
A longitudinal wave travels along a slinky. How should a student measure the wavelength of this wave?
On a guitar string, a pulse travels toward the bridge while one marked spot moves above and below its rest position. What wave type is traveling on the string?
A line of toy cars is bumped from one end, making cars bunch together and spread apart in the same direction the disturbance moves. What wave type is modeled?
In a transverse wave diagram, the highest point is marked with a dot. What is this part called?
A transverse wave diagram has its lowest point marked below the rest line. What is this part called?
In a slinky model, several coils are crowded close together as the wave moves forward. What is the crowded region called?
In a longitudinal wave model, a section of slinky coils is spread farther apart than normal. What is this spread-out region called?
A transverse wave diagram shows the distance from one crest to the next crest. What wave property is being measured?
A sound wave travels straight from a speaker to a wall. Which particle-motion description matches the air as the sound passes?
A transverse wave moves east across a rope. Which motion should a marked bead on the rope show?
A longitudinal wave moves through a spring from left to right. Which particle-motion diagram would match the spring coils?
Ripples crossing a pond have a wavelength of 0.5 meters. A buoy bobs up and down 2 times each second as they pass. How fast do the ripples travel?
A student shakes a rope up and down, then sends sound through air from a speaker. Which comparison is correct?
A teacher compares a water ripple with a push-pull slinky wave. The cork on the water bobs, and the slinky coils move forward and back. Which comparison fits?
