Energy/waves

When the particles of a medium are vibrating perpendicular to the direction of energy transport, then the wave is a ______________ wave.

• longitudinal
• Transverse
• sound
• light

A sound wave is a mechanical wave, not an electromagnetic wave. This means that

• a medium is required in order for sound waves to transport energy.
•  particles of the medium move perpendicular to the direction of energy transport.
• a sound wave transports its energy through a vacuum.
• a sound wave is bad for us

When the particles of a medium are vibrating perpendicular to the direction of energy transport, then the wave is a ______________ wave.

• transverse
•  Longitudinal
• light 
• sound

A __________________ wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport.

• transverse
•  Longitudinal
• light 
• sound

the speed of wave depends on?

• the crest
• the heat
• the amplitude
• the medium

Heat is:

• how cold or hot something is
• how something changes temp.
• The transfer of thermal energy
  

the height of the wave depends on the frequency  

• False
• true

Through which material will a mechanical wave be able to transport the most energy?

• Liquid
• solid
• gas

Transfer of heat flows from

• sound
• Objects that are the same temperature.
• Warmer objects to cooler objects
• Heat does not transfer, it just moves.

frequency means that how frequent something is happening 

• false
• true
