QuestionAnswer
What is a wave? A disturbance that travels from one place to another transporting energy, but not necessarily matter, along with it.
What is a medium? A material through which a wave travels.
What is a transverse wave? A waves that move the medium at right angles to the direction in which the waves travel.
what is a crest? Highest point of a wave.
What is a trough? Lowest point of a wave.
what is a longitudinal wave? A waves that move the particles of the medium parallel to the direction in which the waves are traveling.
What is a compression? The part of a longitudinal wave where the particles of the medium are close together.
What is a rarefaction? The part of a longitudinal wave where the particles of the medium are farther apart.
What is a mechanical wave? Waves that require a medium through which to travel.
What is a amplitude? Maximum distance a wave varies from its rest position.
What is a wavelength? A Wavelength is a distance between two corresponding parts of a wave.
What is a frequency? How many waves can pass a given point per second, measured in Hertz (Hz).
What is a hertz? The unit used to measure frequency.
What is a vibration? A repeated back-and-forth or up-and-down motion.
What is a force? A push/pull exerted in an object to change the motion of it. (Newtons)
What is a work? Work is done when a force causes an object to move in the same direction that force is applied. ( Joules)
What is a power? The rate of getting stuff/things done. ( Watts)
What is a wave speed? The speed that a wave travels.
What is a electromagnetic wave? A transfer wave that involves electric and magnetic energy.
Jake, who weighs 680 n, climbs a 6 meter ladder in 8 seconds. what was Jake's power? 510 watts
running up a flight of stairs, Rosemary generates 450 watts of power. if it takes her 6 seconds to go up the stairs, the amount of work she does in running up the stairs is 2,700J
When waves travel through a medium, what happens to the medium? The waves do not carry the medium with them.
Give an example of a wave that can travel through empty space sunlight (electromagnetic waves)
how are mechanical waves produced? when a source of energy causes a medium to vibrate.
What can act as a medium? solids, liquids, gases
What can be compared to compression and rarefaction in a transverse wave? Crest and trough
If 360 Joules of work are needed to move a crate a distance of 4 meters, what is the weight of the crate? 90N
