1.
Which statement correctly describes soundproofing?
the use of soft materials to reduce sound passing through or reflecting
the taking in of sound energy by a soft surface
a system that uses reflected sound to find the depth of water or objects in it
the bouncing of a sound wave off a hard surface
2.
Which statement correctly describes echo?
sound too high in frequency for humans to hear, used in medical scans
the bouncing of a sound wave off a hard surface
a sound heard again after it has reflected from a surface
the use of soft materials to reduce sound passing through or reflecting
3.
Which statement correctly describes sonar?
sound too high in frequency for humans to hear, used in medical scans
a system that uses reflected sound to find the depth of water or objects in it
the bouncing of a sound wave off a hard surface
the taking in of sound energy by a soft surface
4.
Why is a clear echo more likely in an empty hall than in a room with thick curtains?
Hard surfaces reflect sound well, while curtains absorb more sound
Curtains make sound travel faster than light
An empty hall contains no air
Soft materials create stronger reflected waves
5.
Which statement correctly describes reflection of sound?
the taking in of sound energy by a soft surface
the bouncing of a sound wave off a hard surface
a system that uses reflected sound to find the depth of water or objects in it

6.
Which statement correctly describes absorption?
the use of soft materials to reduce sound passing through or reflecting
sound too high in frequency for humans to hear, used in medical scans
the taking in of sound energy by a soft surface
a sound heard again after it has reflected from a surface
7.
Why might acoustic panels be placed on a classroom wall?
To absorb some reflected sound and reduce unwanted echoes
To increase every echo
To remove the need for air
To make sound travel only vertically
8.
Which practical work belongs to Reflections Of Sound?
Use particle models and demonstrations to compare sound through different media
Relate plate-boundary movement to earthquakes, subduction, volcanoes and fold mountains
Interpret cross-sections and use matching evidence such as fossils, rocks and coastline patterns
Model echoes and apply reflection ideas to echolocation and room acoustics
9.
Which statement correctly describes ultrasound?
the use of soft materials to reduce sound passing through or reflecting
a system that uses reflected sound to find the depth of water or objects in it
sound too high in frequency for humans to hear, used in medical scans
a sound heard again after it has reflected from a surface
10.
A person hears an echo 0.8 s after shouting. Why does the sound travel to the wall and back?
The sound wave is reflected by the wall
The wall creates the original shout
The air stops vibrating
The sound changes into electricity
11.
An echo returns sooner from wall A than from wall B. Assuming the speed of sound is unchanged, what is the best conclusion?
Wall A is closer
Wall A is farther away
Wall B absorbs no sound
Sound travels through wall A at zero speed
12.
How do bats use reflected sound?
They detect echoes to estimate the position of objects
They use sound to make objects invisible
They stop sound from travelling through air
They convert every echo into light
13.
Which statement best expresses the lesson objective about Reflections of sound?
Explain that sound waves can be reflected
The terms echo and reflected are always interchangeable
Evidence is unnecessary when studying Reflections of sound
Every model is an exact copy of reality
14.
Which surface is likely to produce the strongest sound reflection?
A large smooth concrete wall
A thick soft curtain
A deep layer of foam
A pile of wool blankets
15.
