Waves in action
100

Sound travels at 358 m/s in hot desert air but only 330 m/s in cold polar air. This happens to sound as temperature decreases.

What is the speed decreases?

100

Light bouncing off a mirror is an example of this interaction.

What is reflection

100

Between air and water, light travels faster through this medium.

What is air?

100

A scientist performs the same experiment several times. This is called this.

What is repetition?

100

You hear someone knocking on a door more clearly when you place your ear against the door. Sound travels well through this state of matter.

What is a solid

200

Sound travels about 340 m/s in air but about 1,440 m/s in water. This factor affects how fast sound travels.

What is the medium?

200

Solar panels take in sunlight. This interaction with light is occurring.

What is absorption?

200

Light bends when it enters water because this property of the light changes.

What is speed?

200

A different scientist performs another scientist’s experiment. This is called this.

What is replication?

200

A swimmer underwater hears a boat motor because sound can travel through this medium. 

What is water

300

Sound travels fastest through this state of matter because its particles are packed closely together.

What are solids?

300

Light passing through a clear window is an example of this interaction.

What is transmission?

300

A green frog appears green because its skin does this to green light.

What is reflects it?

300

A chemist times the same chemical reaction five times. This scientific process is used.

What is repetition?

300

A coin at the bottom of a pool appears to be closer to the surface than it really is because of this light behavior.

What is refraction?

400

An astronaut sees an explosion in space but hears nothing because sound cannot travel through this.

What is a vacuum?

400

A straw looks bent when placed in water because of this interaction of light.

What is refraction?

400

An object that does not produce its own light can still be seen because it does this to light.

What is reflects light?

400

Several scientists separately perform the same wombat experiment and compare their results. This is an example of this.

What is replication?

400

A black shirt becomes hotter than a white shirt in sunlight because the black shirt does more of this to light energy.

What is absoption?

500

You see a baseball hit before you hear the crack because this type of wave travels faster than sound.

What is light?

500

A ball bouncing off the floor at an angle can be used to model this light behavior.

What is reflection?

500

When light travels from glass into air and bends, this process is occurring.

What is refraction?

500

One scientist repeats an experiment many times, and months later another scientist performs the same experiment in a different laboratory. The second scientist is doing this.

what is replication

500

During a thunderstorm, you see lightning several seconds before you hear thunder. This happens because these two waves travel at different speeds.

What are light and sound waves
