Wave Speed
Mechanical waves simply cannot travel through this medium.
What is a vacuum or empty space?
This is the most powerful, energetic wave on the EM spectrum.
What are gamma rays?
The bending of waves as they pass through a new medium because they change speed and direction.
What is refraction?
The frequency of this pitch sound is very high!
What is a high pitched sound?
These colors, combined in equal parts, make up visible white light.
What is ROY G BIV?
Sound waves pass quickly through these types of objects.
What is the a solid?
The frequency of a wave increases as this decreases.
What is wavelength?
I shined a light onto a mirror and saw this waves interaction.
What is a reflection?
Sound is made up of these mechanical waves.
What are longitudinal waves?
Combined red, blue and green lights in equal proportions gives us this color of light.
What is white light?
This kind of waves travels faster in a vacuum than through the air.
What is an electromagnetic wave?
This EM wave can give you a nasty sunburn, dude.
What is an ultraviolet wave?
When I stand close to a fire, the infrared energy will do this in my skin and make me feel warm.
What is absorb?
Sound travels slowest in this medium.
What is the air or a gas?
If I see a blue shirt, the shirt must absorb all wavelengths of color except this one, which it reflect.
What is blue?
Longitudinal waves move through different media at different rates. List the three states of matter according to how fast longitudinal waves move through matter from slowest to fastest?
Solid, liquid, gas
These two kinds of EM waves can be used in a hospital. One can kill cells and one can see through cells.
What are x-rays and gamma rays?
What type of wave interaction enables bats and other animals to use sonor to find food?
What is reflection?
We expect sound to travel faster through this temperature medium.
What is a hot or a warmer temperature?
Visible light waves move through different media at different rates. List the four mediums through which light can travel according to how fast visible light waves move through matter from slowest to fastest?
vacuums, air, liquid, solid
Would an underwater whale song or a song playing in your car travel faster? Justify your response.
(use the word 'particle' and 'vibration' in your answer)
The sound would travel faster in the water because sound travels faster in water than air since there are more particles in liquids.
Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. Which is a logical conclusion about these electromagnetic waves?
(use 'medium' in your response)
They can travel through space and do not require a medium.
Compare the energy of a sound wave with a wavelength of 12cm to a sound wave with a wavelength of 10cm.
(Use 'frequency' and 'energy' in your answer)
The frequency of the 12 cm wave is lower than the 0 cm wave. The 10 cm wave has more energy.
Describe how sound waves are produced.
(Use 'particles' in your response)
Particles vibrate which produces longitudinal waves that we can hear.
A dog is far away. You see it barking at a kid passing by. From far away, would you expect to SEE the dog’s mouth move or HEAR the dog’s bark first?
I would expect to see the dog bark before I hear him since light, which helps me see, travels faster than sound through the air.
