QuestionAnswer
the buoyant force equals the objects weight
what is a complete cycle of motion period
number of cycles or vibrations per unit of time frequency
at a fixed boundary, waves are reflected and inverted
standing waves are produced by periodic waves of the same frequency, amplitude and wavelength traveling the opposite direction
sound waves are what kind of waves longitudinal waves
what is the region of a longitudinal wave in which the density and pressure are greater than normal compression
how high or low we perceive sound is called pitch
what generally travel faster through solids than liquids? sound waves
when the frequency of a force applied to a system matches the natural frequency of vibration of the system resonance
when 2 tuning forks side by side that emits frequencies that differ by only a small amount beats
relationship between frequency wavelength and speed holds for light waves because all forms of electromagnetic radiation travel at a single speed in a vacuum
image created by a flat mirror virtual upright and magnification=1
refraction is the term for the bending of a wave disturbance as it passes at an angle from one ____ to another medium
the _____of light can change when light is refracted because the wavelength changes color
what will happen to a light ray incident on a glass-to-air boundary at greater than the critical angle total refraction
a repelling force occurs between two charged objects when charges are like signs
when a glass rod is rubbed with silk and becomes positively charged electrons are removed from the rod
where is the magnitude of the magnetic field around a permanent magnet greatest close to the poles
a current in a long straight wire produces a magnetic field. These magnetic fields lines form circles that go around the wire
in a magnetized substance, the domains line up mainly in one direction
whose principle says as the velocity of a fluid increases, its pressure decreases Bernoulli's
whose principle says the pressure in a confined fluid increase remains the same throughout Pascal's
whose principle says the buoyant force on an immersed object is equal to the weight of the fluid it displaces Archimedes

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
