# waves in physics

v= f x lamda (upside down y) wave speed
bottom of a wave trough
the distance between identical points on 2 adjacent waves wavelength
the distance between the top (or bottom) to the resting position on a wave amplitude
the material that a mechanical wave passes through medium
wave that can travel through a vacuum (do not need a medium) electromagnetic
interference from "in sync" waves that add up constructive
wave hitting a surface and bouncing back into medium reflection
the time it takes to complete a wave cycle (T) period
the number of cycles completed in a certain period of time (f) frequency
T = 1/f formula for period
interference from "out of sync" waves that cancel each other out destructive
EM band with longest wavelength and lowest frequency radio waves
EM band with shortest wavelength and highest frequency gamma rays
f = 1/T formula for frequency
speed of light 3.0 x 10^8 m/s
speed of sound 3.4 x 10^2 m/s

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.
