The medium through which a mechanical wave passes can be a solid, a liquid, or a gas. Properties of a wave might change when it moves from one medium to another. What happens to the speed of a wave when it moves from a gas to a solid?
It speeds up
it slows down
It remains the same
it speeds up and then slows
Electromagnetic energy travels in waves. These waves can vary in their frequencies and wavelengths. Electromagnetic energy is classified by the length and frequency of its wave. Of the four wave types below, which has the highest frequency?
Microwaves
Infrared waves
gamma rays
radio waves
When you listen to the radio, watch TV, or cook food in a microwave, you are using a device that makes use of man-made electromagnetic waves. Which statement about electromagnetic waves is false?
Electromagnetic waves travel at the speed of light in a vacuum.
Electromagnetic waves need a medium to travel through.
Different wavelengths of visible light are interpreted by our eyes as different colors.
The transfer of energy as electromagnetic waves is called electromagnetic radiation.
How does a longitudinal wave tend to move?
back and forth
up and down

Which of these properties allows you to see the moon at night, see yourself in a mirror and hear an echo
reflection
refraction
diffraction
interference
What is a medium?
a disturbance in the magnetic field that is a transverse wave
a disturbance that transfers energy from one place to another
the material through which a wave travels like gas, liquid, solid
What is a mechanical wave?
a wave that requires a medium through which to travel like gas, liquid or solid
a wave that does not need a medium to travel through like moving through the vacuum of space
What is a longitudinal wave?
the motion is up and down as the wave passes
the motion is back and forth in the same direction as the wave travels
a wave that can move without a medium like through the vacuum of space
