Sound does not travel in space because
The particles in a vacuum are too far apart for sound to bounce off of.
There is not matter in space.
Stellar gases get in the pathway of sound waves.
This statement is incorrect, sound does travel in space.
Mechanical wave is defined as the waves produced by a disturbance in a
medium causes the vibration of particles in the medium to ________________________________
transfer the electromagnetic
transfer the energy.
transfer the heat

Jhadin claims that waves cannot travel through the vacuum of space. Caleb argues that Jhadin is incorrect. Which statement should Caleb use as evidence?
Matter travels from the sun to Earth.
Sound waves travel from the sun to Earth.
Longitudinal waves travel from the sun to Earth.
Electromagnetic radiation travels from the sun to Earth.
Which of the following correctly lists electromagnetic waves in order from highest to lowest frequency?
gamma, X-rays, UV, visible light, infrared, microwaves, radio waves
microwaves, infrared light, UV, gamma, visible light, radio, gamma
gamma, visible light, UV, X-rays, infrared, microwaves, radio waves
radio waves, micro, red, visible light, UV, X-rays, gamma.
What type of electromagnetic waves are created by the sun?
sound
ultraviolet and visible only
ultraviolet, visible, and infrared only
all seven types of electromagnetic waves
What happens to a light wave that is absorbed by matter?
It is reflected from the surface of the matter.
It is refracted.
It bends around the matter.
Its energy is turned into heat.
Which material is light able to travel faster through? Explain.
Vacuums of empty space because there are no particles for the light to have to bounce around.
Gases because the particles are less packed together so the light waves can move quickly through it.
Liquids because the particles easily slide around on each other so the light waves can slide with the liquid particles.
Solids because the particles are closely packed together and the light waves can bounce off of each particle quickly.
Based on the data table, which material do you think sound would travel the fastest through?
carbon dioxide
liquid H2O
solid H2O
liquid nitrogen
Electromagnetic waves vary in
the speed they travel in a vacuum
wavelength and frequency
the way they reflect
the orientation of their electric and magnetic fields
A student asks a series of questions about a wave. The answer to which question will allow the student to determine whether the wave is electromagnetic or mechanical?
Does it require a medium in order to travel?
Can it pass through air and water?
Does it have a measurable speed?
Does it have a measurable frequency?
How do electromagnetic and mechanical waves compare?
Mechanical waves can only travel through a vacuum, but electromagnetic waves can travel through a solid, liquid, or gas.
Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a gas.
Mechanical waves can only travel through a solid, liquid, or gas, but electromagnetic waves can travel through a vacuum.
Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a solid.
What makes electromagnetic waves different from mechanical waves?
no medium required
medium needed
light -catalyzed
space exclusive
Waves that require a medium are known as
Medium waves
Mechanical waves
Air waves
Heat waves
