What is the biggest difference between mechanical waves and electromagnetic waves?
EM waves, like sound, require matter to travel, while mechanical waves, like light, can travel through a vaccum.
EM waves can only travel through gases and liquids, while mechanical waves can only travel through liquids and solids.
Mechanical waves, like sound, need matter to travel, while EM waves, like light can travel through a vacuum.
EM waves can travel in compression waves that you hear and mechanical waves are transverse waves you can see.
What is being modeled in this image?
Sound waves only because light doesn't do this
Both sound and light waves.
Just light waves because sound can only be scattered by glass
Light and sound waves cannot interact at the same time.
Which of these best describe a longitudinal wave?
particles move at a right angle to the wave
transverse waves include EM waves
include compressions and rarefactions
include crests and troughs
particles move parallel to the wave
Which of these best describe a transverse wave?
particles move at a right angle to the wave
transverse waves include EM waves
include compressions and rarefactions
include crests and troughs
particles move parallel to the wave
Which describe a longitudinal wave?
particles move parallel to the wave
include crests and troughs
include compressions and rarefactions
include sound waves
What is the relationship between energy and EM waves?
the more energy a wave carries, the more dangerous it is
waves with high energy occur less often
waves with low energy have the shortest wavelength
energy is not in the EM spectrum
Which shows the waves from least energy to most energy?
micro, gamma, infrared, x-ray
gamma, UV, infrared, radio
Visible, micro, x-ray, gamma
radio, infrared, UV, gamma
What happens to EM waves if you increase the frequency?
energy increases, wavelength decreases
energy and wavelength decrease
energy and wavelength increase
energy decreases, wavelength increases
What is the relationship between the EM spectrum and energy?
there isn't one
wavelength is inversely proportional to energy
energy decreases as you move from left to right
wavelength is directly proportional to energy
Which wavelength is used to detect thermal energy?
UV

Why is a shamrock shake green?
green light is absorbed
green light is refracted
green light is reflected
green light is diffracted
Why does a straw look broken when it's in a glass of water?
surface tension is disturbed
the pencil slows down the light waves
light waves are diffracted by water
light waves cannot be transmitted through water
How does echolocation work?
waves bend around barriers
two waves combine and form a new one
waves bend when they hit an obstacle
waves bounce back when they hit an obstacle
What does a prism do?
separates white light by reflecting the different wavelengths
separates white light by reflecting each wavelength in a different direction
separates white light by refracting each wavelength a different amount
separates white light by absorbing certain wavelengths and transmitting others
Which has the greatest effect on how much light is refracted?
the distance that the light has to travel in each medium
the color change in the light
the difference in mass of the materials
the difference in density of the materials
Why does sound travel faster through metal than gas?
the particles in the metal are far apart and moving fast
the particles in gases are closer together than in metal
the particles in metals are closer together than in gas
the particles in gases are denser and slower
In order for sound to travel, particles must be present. The closer they are, the faster sound travels. This explains what?
that sound travels faster in air than water
that sound travels faster in water than metal
sound travels faster in metal than water
sound travels faster in space than air
One wave at the beach has a crest that is 2 feet high. The next one has a crest of 6 feet high. The second wave has a greater
amplitude
frequency
compression
wavelength
If you hit a tuning fork with soft rubber, then hit it on a hard surface, the fork will produce a higher sound. Why?
the soft rubber creates higher energy - increasing amplitude and frequency
the hard surface creates lower energy - increasing wavelength and frequency
the hard surface creates higher energy - increasing amplitude and frequency
the soft rubber creates lower energy - increasing wavelength and frequency
