Nature of Waves | Characteristics of Waves | Light matters | Do you hear what I hear? | Miscellaneous |
---|---|---|---|---|
Energy
Waves carry
|
Crest
High point on a transverse wave is called the
|
All the colors of the rainbow
What does white light contain?
|
Vibrations
Sounds are created by
|
Refraction
This is responsible for causing rainbows to appear
|
Medium
Some waves have to travel through this
|
Amplitude
This is the term for the height of the wave
|
Radio waves
This EM wave has the longest wavelength and lowest frequency
|
Increases
As temperature increases, speed of sound ________
|
Echo
When a sound wave reflects, we call it ________
|
Longitudinal/sound
This type of wave requires a medium to travel through.
|
Compression
This is a section of longitudinal wave where the particles are pushed together
|
Reflected
Yellow light is _______ when white light shines on a lemon.
|
Volume/loudness increases
As amplitude of a sound wave increases, what happens?
|
Baby screaming, trumpet, piccolo
Give an example of a high amplitude, high frequency sound wave
|
Light
Electromagnetic waves are also known as ________ waves.
|
Low, long
A wave with low energy has ______ frequency and _____ wavelengths
|
Strong enough to penetrate skin and muscle but not the bone
Explain how an x ray works
|
Africa, deserts, hot places
Where in the world might the speed of sound travel the fastest?
|
Reflected, absorbed, bent
Light can be ____, _______, or _______ when it hits an object.
|
Amplitude, frequency, energy
ALL waves have these 3 things
|
Wavelength and frequency
Electromagnetic waves are classified by these 2 properties
|
Gamma rays have high energy that can kill cells while radio waves are incredibly low energy waves
Why are gamma rays so dangerous and radio waves so harmless?
|
No, because there is no medium for particles to vibrate through
If something explodes in space, does it make a sound?
|
Refraction bends the light
Why is it hard to aim for something that you need to grab out from under water?
