Defining Light & Sound
This is a form of electromagnetic energy that travels in a straight line and can be detected by our eyes.
What is light?
This massive, natural celestial body is Earth's primary source of natural light.
What is the Sun
This optical phenomenon occurs when light waves hit a surface and bounce right back off it.
What is reflection
This property is determined by counting the exact number of sound vibrations that occur per second.
What is frequency
This massive star is our solar system's ultimate producer of both immense light and immense heat.
What is the Sun?
This type of energy is created when something vibrates and sends waves into our ears.
What is sound?
Common in household lamps, this everyday object is a primary example of an artificial light source.
What is a light bulb?
This happens when light waves hit an object and completely stop, converting into energy rather than passing through or bouncing off.
What is absorption
While thunder or a bass drum produces low frequencies, this common chirping backyard insect produces a distinctly high-pitched sound
What is a cricket
Often built using logs out in the woods, this source provides a campsite with both illumination and warmth
What is a fire
These are invisible waves that move up and down very quickly, acting as the root cause of all sounds.
What are vibrations?
This bioluminescent insect is a unique, living example of a natural light source.
What is a firefly?
This term describes the bending of light as it passes through a transparent or translucent object.
What is refraction
These safety devices are inserted directly into the ear canal to protect a person from suffering hearing damage in loud environments.
What are earplugs
Made of wax and a wick, this classic household item produces a small flame that generates both light and a steady amount of heat.
What is a candle
This term describes how humans interpret and hear pressure changes caused by sound waves.
What is loudness?
Handheld and battery-powered, this item provides artificial light on demand during a power outage or a nighttime walk.
What is a flashlight
While a clear glass allows light to pass completely, this specific type of material—like frosted glass—scatters the light, making it translucent.
What is translucent
Unlike earplugs which dampen sound, this type of electronic device does the exact opposite by increasing the volume and strength of audio signals
What is an amplifier
Unlike a blazing fire, this pocket-sized technology utilizes a cool LED that produces light but is specifically noted for not generating significant heat.
What is a phone light?
Clocking in at an incredible pace, this specific measurement is the exact speed of light.
What is 300,000 kilometers per second?
Unlike the sun, this modern screen-based device requires electrical power to create artificial light
what is a computer screen
Campfires and flashlights emit light, but this nighttime object only appears to shine because it does this to the sun's rays.
What is reflects light? (or What is the Moon?)
If a high frequency creates a high pitch, this is the type of sound pitch created when vibrations per second are very low.
What is a low pitch?
The moon reflects light, but this part of a feline's face is famous for reflecting light in the dark without producing any heat of its own.
What are cat's eyes?
