Total questions: 20
Worksheet time: 11mins
Which type of matter is likely to absorb the most sound waves?
Metal door
Loudspeaker
Hot air
blanket
In which situation are waves transmitted?
A camp fire lights up a cave.
Ice cream melts on a hot day.
Leaves look green in sunlight.
A curtain blocks light from a window.
Through which material would you expect sound waves to move fastest
Air
Iron
milk
water
Lightning is seen before its associated thunder is heard. This is because light waves travel faster in air than sound waves do.
Through which material would sound waves move faster than light waves?
Liquid water
Helium gas
Solid bronze metal
Oxygen gas
What causes a sound wave to echo in an empty house?
Reflection of waves off smooth walls
Absorption of waves by rough walls
Refraction of waves by a person speaking
Transmission of waves from a person speaking
What causes a spectrum of colors to appear when light moves through a prism?
Reflection of light waves
Absorption of light waves
Transmission of light waves
Refraction of light waves
Which observation is evidence of refraction in this photo?
The water in which the man is swimming is transparent.
The man's arm is clearly seen under the water.
The top of the man's head appears disconnected from the rest of his head.
The snorkel in the man's mouth appears yellow.
Which observation provides evidence that some kinds of mediums can bend light waves?
Green plant leaves absorb red light waves found in sunlight.
Different colors of light refract at different angles when passed through a prism.
Light waves travel at a speed of about 300,000,000 m/s in empty space.
A clear glass window allows people to see what is happening on the other side.
What happens when a wave enters a different material and slows down?
Absorption
Refraction
Reflection
Transmission
What causes a wave's path to bend when it bounces off the surface of a material?
Transmission
Refraction
Absorption
Reflection
Mark Zuckerberg based his development of Facebook on which need or want?
To help people avoid having to talk to others in social situations
To allow people to share photos online without keeping a record
To allow people to connect online like they do in person
To help people learn more about their friends' habits and opinions
Radio waves bounce off objects and can be tracked. The photo shows one way this technology is used today.
Which need, want, value, or interest was most likely involved in the development of the device shown?
A safe and fair driving environment
A well-funded police department
A way to read license plates from afar
A lack of parking spaces for cars
This image of a baby was produced using ultrasound.
Which option is the best model of how the image was made?
A turbine
A convex lens
An echo
An X-ray
Which two technologies use reflected sound waves?
Solar panels
Sonar
Radar
Ultrasound imaging
Which two technologies use waves to determine the location and velocity of objects?
Radar
Sonar
X-rays
Lenses
Which two technologies use lenses?
Radar
Ultrasound
Telescope
Microscope
A vinyl record has grooves carved into it that match the original sound waves. A CD uses digital versions of the original sound waves.
Why might a CD be a more reliable way to copy and distribute a sound recording than a vinyl record?
A CD fails to accurately replicate the original sound waves.
A CD is easier to copy exactly over and over again.
A CD can easily lose information because of noise.
A CD uses a greater number of possible values to encode data.
Why can a digital signal send a message over a very long distance more reliably than an analog signal?
The digital signal is less vulnerable to noise and more likely to arrive intact.
The digital signal has waves that curve gradually and have many values.
The digital signal could easily lose information because of noise.
The digital signal loses quality when copied over and over.
The photograph shows a type of wave technology.
Which need or want does this technology meet?
It allows people to measure the speed of objects.
It allows people to rapidly heat items
It allows people to rapidly freeze items.
It allows people to see very small objects clearly.
Email uses wave technology. What is the main need or want this technology meets?
To hear and see others in real time
To efficiently store and share music with others
To speak with and see others who are far away
To efficiently communicate with others
