Waves Mini Quiz

Sunlight is slowed MOST when traveling through

• a vacuum.

• the atmosphere

• water

• None of these. Light always travels at the same speed.

Which would be the least effective medium for traveling sound waves?

• vacuum

• solid

• liquid

• gas

Which of these is a TRUE statement?

• Sound travels through solids, liquids, and gases at the same speed.

• Sound sometimes travels easier through gases than solids.

• Sound travels through solids easier than

  liquids.

• Sound travels through gases easier than

  liquids.

Which type of wave would actually slow down when moving from the air into the ocean?

• Sound Waves

• Earthquake Waves

• Light Waves

• Ocean Surface Waves

An old movie poster used a quote "In space, no one can hear you scream!" Why this is true or not true?

• The quote is incorrect, you can hear sound in

  outer space.

• Sound is an electromagnetic wave and needs no medium to travel through.

• Sound cannot be polarized. So, you cannot hear sound in space.

• Sound needs a medium for the wave to vibrate and there is nothing in space to vibrate.

Compression or sound waves behave a lot like transverse or electromagnetic waves. Compression waves exhibit ALL BUT one of the following behaviors. That is

• reflection.

• transfer energy.

• refraction.

• travel through a vacuum.

You see lightning before you hear thunder because

• light waves can travel through a vacuum.

• light waves travel faster than sound waves.

• sound waves cannot travel through the air.

• sound waves travel faster than light waves.

In which medium would sound travel the fastest?

• across a room

• through outer space

• in a swimming pool

• through a railroad track

Why can television satellites, which broadcast information as electromagnetic radiation, send signals from the vacuum of space?

• because electromagnetic radiation increases

  as the distance increases

• because space does not provide a medium that will block the satellite signals

• because electromagnetic radiation does not

  need a medium to travel through

• because space is so vast that light waves can spread out to their full size and strength

The speed of sound waves through two different media, steel and air, was recorded. According to the graph, sound waves travel

• through steel, but not through air.

• faster through steel than through air.

• faster through air than through steel.

• through steel and air at similar speeds.
