What is a wavelength?
the number of waves that pass a point in one second
the distance between two crests or two troughs
the crust of the upper mantle
what is frequency?
less dense than the material below it so it floats
the distance between two crests
the number of waves that pass a point in one second
The cork does not change its position within the wave; instead, it moves up and down in its original position. What can be concluded about mechanical waves from this activity?
Mechanical waves carry the particles of mediums along with the waves.
Mechanical waves can move through empty spaces.
Mechanical waves transfer energy but not matter.
Mechanical waves do not carry energy.
Which wave best demonstrates the wave behavior of absorption?
wave J
wave K
wave L
wave M
Why is sound unable to travel through the window while light can still shine through?
Sound has a different frequency than light, so it cannot pass through the window.
Sound has a different wavelength than light, so it cannot pass through the window.
Light can travel through both the glass and the vacuum, but sound can travel only through the glass.
Light can travel through both the glass and the vacuum, but sound can travel only through the vacuum.
What happens to a ray of white light when it passes through a prism?
The ray of light is combined into a single color.
The ray of light is completely absorbed by the prism.
The ray of light is bent backward toward the source of light.
The ray of light is bent in several pathways showing a rainbow.
What process forms an image in a mirror?
absorbing light
reflecting light
refracting light
transmitting light
What parts of the wave are labeled X and Y?
X represents the compressions; Y represents the rarefactions.
X represents the rarefactions; Y represents the compressions.
X represents the compressions; Y represents the wavelength.
X represents the rarefactions; Y represents the wavelength.
When a pencil is placed in a cup of water, the pencil looks bent. What does this demonstration show?
