# Chapter 1 Waves

### Study for the Chapter 1 waves review.

Frequency= Speed/ Wavelength
Frequency at which a standing wave occurs. Resonant Frequency
Wave that consists of a combination if transverse and longitudinal waves and occurs at the surface between two different mediums. Surface Wave
Wavelength= Speed/Frequency
Speed= Frequency x Wavelength
What occurs when vibrations traveling through an object match the object's natural frequency? Resonant Frequency
Why to waves travel through a medium? The energy travels from particle to particle.
When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes Reflection
Why do you see lightning from a distant storm before you hear thunder? Light travels faster than sound.
Compressions and rarefractions are characteristic of what type of wave? Longitudinal Waves
Waves combine to produce a smaller or zero-amplitude wave in a process called Destructive Interference
The distance between two consecutive crests of a wave is called the Wavelength
What is frequency measured in? Hertz
How are mechanical waves classified? According to how they move
The bending of waves around the edge of a barrier is known as Diffraction
The beding of waves due to the change in speed is called Refraction
The speed of a wave is 20 m/sec. If the wavelength of the wave is 2 meters, what is the frequency of the wave? 20m/s divided by 2m= 10Hz
A wave has a frequency of 10Hz and velocity of 5m/s. What is the wavelengthof this wave? 5m/s divided by 10hz= 0.5m
A wave with a frequency of 20Hz has a wavelength of 10 meters. At what speed will this wave travel? 20Hz times 10m= 200m/s
A wave with a frequency of 40Hz has a wavelength of 20 meters. At which speed will this wave travel? 40Hz times 20m= 400m/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.
