# Wave Basics

what is Amplitude? rest position to the crest
what is wavelength? from crest to crest
what is the frequency? the number of complete waves passing a certain point per second . measured in hertz (Hz) 1Hz is 1 wave per second
what are Transverse waves? they have sideways vibrations. most waves are transverse the vibrations are perpendicular (90 degrees) to the direction of energy transfer of the wave
what are longitudinal waves? they have vibrations along the same line the vibrations are parallel to the direction of energy transfer of the wave
give 4 examples of transverse waves 1. light and all other EM waves 2. ripples on water 3. waves on strings 4. a slinky spring wiggled up and down
give 3 examples of longitudinal waves 1. sound waves and ultrasound 2. shock waves 3. a slinky spring when you push the end
how do you find wave speed/velocity? frequency x wavelength

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
