Ohio AIR Light & Sound Review

Ohio AIR Light & Sound Review

Multiple Choice

Light and sound are both forms of energy.

• True

• False

Light travels and maintains its direction until it interacts with an object or moves from one medium to another and then it can be reflected, refracted or absorbed.​

​Light

Sound is produced by vibrating objects and requires a medium through which to travel. The rate of vibration is related to the pitch of the sound.​

​Sound

Light and sound are forms of energy that behave in predictable ways.

Multiple Choice

Sound needs a ____________ in order to move.

• speaker
• ears
• medium
• person

Multiple Choice

What causes sound?

• something vibrating
• a part of a car
• an object moving through the air
• light energy

​Pitch can be changed by changing how fast an object vibrates. Objects that vibrate slowly produce low pitches; objects that vibrate quickly produce high pitches.​

Multiple Choice

What is frequency?

• the number of vibrations per second
• how high or low a sound is
• the loudness or softness of a sound
• the back and forth movement of matter

Multiple Choice

The frequency of vibrations affects the ____of a sound.

• color

• pitch

• light

Multiple Choice

A teacher makes a model guitar by using an open box for the guitar body and rubber bands for the strings. Students observe that the pitch of the sound produced by each rubber band depends on how tight the rubber band is.

Based on your understanding of pitch, what is a possible reason that the tightness of a rubber band can change the pitch of sound?

• It makes the rubber band vibrate faster or slower

• It makes the rubber band vibrate in different directions

• It makes the rubber band vibrate more loudly or more softly

• It makes the rubber band vibrate for different lengths of time

Multiple Choice

What happens to a sound if the frequency of the vibrations increases?

• the volume decreases
• the pitch increases
• the sound echoes
• the sound gets louder

Multiple Choice

High pitches are produced by objects vibrating _______________.

• quickly
• slowly

Multiple Choice

The highest pitch is made by the _______ instrument.

• biggest
• wooden
• smallest
• shiniest

Multiple Choice

The longer the string on an instrument, the _________ the pitch.

• lower
• higher
• softer

Multiple Choice

Which bar on the xylophone would produce the highest pitch?

• Green

• Purple

• Red

• Orange

​Sound must travel through a medium to move from one place to another. This medium may be a solid, liquid or gas. Sound travels at different speeds through different media. ​

​

​

Sound

Multiple Choice

Which material does sound travel through the fastest?

• air 
• outer space
• water
• brick

Multiple Choice

Rank the speed of sound through different mediums from the fastest to slowest

• solid --> liquid --> gas

• liquid --> gas --> solid

• gas --> liquid --> solid

• solid --> gas --> liquid

​

Once sound travels outward in all directions until it reaches a different medium.

​

When it encounters this new medium, the sound can continue traveling through the new medium, become absorbed by the new medium, bounce back into the original medium (reflected) or engage in some combination of these possibilities

Sound

Multiple Choice

Why do musicians cover their music studios in foam padding?

• Soft objects absorb sound the best

• Soft objects reflect sound the best

• In case they want to take a nap

• So they do not hurt themselves on accident

Multiple Choice

If a sound bounces back it is called ______________.

• frequency
• sound
• pitch
• an echo

Multiple Choice

What is volume?

• how high or low a sound is
• the loudness or softness of a sound
• the number of vibrations per second
• vibrations

Light Behavior

Light travels and maintains its direction

until it interacts with an object or moves

from one medium to another and then it

can be reflected, refracted or absorbed.

Light bending due to the speed of light varying speed depending on the material it passes through

​

​Refraction

Light bouncing off of a surface. Usually off a shiny object such as mirror or body of water

​

​Reflection

Multiple Choice

Reflection occurs when...

• light goes through a surface
• light strikes a surface and bounces back

Multiple Choice

Which of these processes does the picture illustrate?

• reflection
• refraction
• absorption
• scattering

Multiple Choice

Which diagram BEST illustrates the reflection of light from the surface of a mirror?

• A
• B
• C
• D

Multiple Choice

A student wants to set up a demonstration to show how white light can be refracted.

Which tool should the student use for her demonstration?

Multiple Choice

In tropical locations, the roofs of homes are often painted white to prevent the temperatures inside the home from getting too hot.

Which statement explains how white roofs keep the temperatures lower inside homes?

• The white paint reflects the sunlight

• Sunlight refracts through the white paint

• Sunlight is absorbed and trapped in the white paint

• The white paint allows sunlight to travel through the roof
