Chapter 12 Flashcards
The amplitude of a wave is____.
Height from the middle ( rest position) to the crest.
Frequency is ___(units of____or___)
The number of wave cycles per second. Units: “/s” or cycles/sec or Hz.
The wavelength is the distance from___
Crest to crest or trough to trough or any full cycle distance.
The period of a wavelength is___.
How long it takes a wave to pass by. Units: “s” or seconds/cycle (time for one wave to pass)
Waves transfer_____from one place to another.
Energy
For the same type of wave, a longer period has a (longer or shorter?) wavelength.
Longer
For the same type and speed of wave, a longer period has a (higher or lower?) frequency.
Lower
All of the types of waves that Do Not require a medium are classified as ___.
Electromagnetic waves
For the same type and speed of, a longer wavelength has a (higher or lower?) frequency.
Lower
For the same type and speed of wave, a higher amplitude wave has a (higher or lower?) energy.
Higher
Light is a (transverse, longitudinal, or surface?) wave.
Transverse
Light is a (electromagnetic or mechanical) wave.
Electromegnetic
