Waves

QuestionAnswer
As the wavelength increases, the frequency_________. Decreases
Which wave interaction explains why sound waves can be heard around corners? Diffraction
What does the law of reflection state about the angle of incidence? It is equal to the angle of reflection
A place where you would ear the most clear echo would be one that has what type of surface? Flat, hard, smooth
What unit is used to measure loudness? Decibels
What wave interaction allows us to see rainbows? Refraction
Why does refraction occur when a wave enters a new medium at an angle? The wave speed changes
A wave that is a combination of longitudinal and transverse is called_________. Surface wave
What are waves that do not require a medium? Electromagnetic waves
What determines the loudness of a sound? Amplitude
When looking at a longitudinal wave, the section where the particles are crowded together is called? A compression
What is the name of the wave where particles vibrate at right angles to the direction that the wave is traveling? Transverse waves
What is the equation for the speed of a wave? Speed = wavelength x frequency
The maximum distance a wave vibrates from its rest position is called______. Amplitude
The distance between any two adjacent crests or compressions is called_______. Wavelength
The number of waves produced in a given amount of time is called the ________ of a wave. Frequency
What is the result of destructive interference? A smaller amplitude than the original waves
What is the result of constructive interference? A larger amplitude than the original waves
What is the most important wave interaction for echolocation? Reflection
What does the speed of a sound wave depend on? The medium it travels through
The complete back and forth motion of a wave is called______. Vibration
What type of wave does sound travel as? Longitudinal wave
The speed of sound in air ________ as the temperature decreases. Decreases
What happens to sound when constructive interference occurs? A sound will be louder because the amplitude is increased
________ occurs when an object vibrating at or near a specific frequency causes a second object to vibrate. Resonance

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.
