What is opaque?
Something that light can not get through, like a desk
100
Can sound travel through a vacuum?
No
100
Can electromagnetic waves travel through a vacuum?
Yes
100
What is the top of a wave called?
Crest
100
If two waves are moving the same direction at different speeds, what happens when the two waves meet?
They momentarily create a bigger wave
200
True or false
Light can be a transverse wave made up of electric and magnetic fields OR it can act like a stream of particles
True
200
What kind of wave is sound?
Longitudinal
200
List the colors of the rainbow from highest to lowest frequency
purple, blue, green, yellow, orange, red
200
Waves bending is called...
Refraction
200
What happens when light moves from air to water?
The light speed decreases, and the light is refracted
300
How could I read something that is written backwards?
With a plane mirror
300
How do sound waves change when moving from air to water
The waves increase speed
300
What do we use visible light for?
Everything we see
300
Do longitudinal waves have rarefaction and compression or crests and troughs?
Rarefaction and compression
300
If the wavelength of the color purple is 350 nm, and the color red is 700 nm, which has a longer distance between the wave crests?
Red has a longer distance because it has a longer wavelength
400
If I put a RED color plastic over an image, what shines through?
Anything with red in in, everything else will be black
400
What is resonance?
When two sound frequencies match
400
Give an example of technology for radio waves, microwaves, infrared, x-rays, and gamma rays
TV, Microwave, radar, X-ray machine, Radiation for cancer
400
Draw a standing wave and label the nodes and antinodes
400
How does an echo happen?
The sound waves are reflected off a surface back to you
500
How is a rainbow formed?
The white light from the sun is refracted through the raindrops and when it comes through, the frequencies of the colors travel differently
500
How would I break a glass jar with my voice?
Match the pitch of the voice to the frequency of the glass
500
How do x-rays work?
The frequency of the wave is fast enough to see through soft material, but not fast enough to see through bones
500
What is a surface wave?
A wave that is both transverse and longitudinal
500
How can you calculate the speed of a wave?
Distance/time
or
wave length X frequency
