Waves Science

SPS9a,b,c,d,e vocab

TermDefinition
Medium any form of matter whose particles transport the wave's energy
Wave a disturbance caused by the mechanical motion of a particle
Propagate travel by the physical motion of particles
Sound wave a form of a mechanical wave
Electromagnetic waves waves that can travel through a vacuum
Mechanical waves waves that require a medium
Vacuum empty space
Transverse wave a wave that oscillates in the direction that is perpendicular to it's movement
Longitudinal wave a wave that oscillates in the direction that is parallel to it's movement
Amplitude the maximum displacement of a wave particle from the midpoint between the crest and the trough
period the amount of time for one cycle of motion to complete
Wavelength the distance between two crests
Hertz the peak of one cycle per second
Frequency The number of wavelengths that occur in a time
the velocity formula Frequency*Wavelength
the symbol for wavelength? Lambda (λ)
Reflection is when waves bounce off of a surface
an example of reflection? Waves bounce from the mirror into your eyes when you look into it
If a wave is only partially reflected what happens to the leftover energy absorbed
When waves travel through matter Transmitted
Reflection waves bounce off the surface at the same angle it hit it
Transmission travels through the material at the same angle it entered
Refraction travels through the material, but now at a different angle
Diffraction travels through the material until an obstacle is encountered. The proceeds to BEND around the object and pass.
Absorption does not travel all the way through the material.
Interference Wave come from 2 sources and meet. They then affect each other in different ways.
Law of Reflection States that the angle of reflection equals the angle of incidence
Angle of Incidence Angle of which light hits the surface
Angle of Reflection Angle that the light bounces off the surface
Refraction does what based on the density of the medium It bends the wave
What is Snells Law n1sinθ1=n2sinθ2
What is Visible Light Light that humans can see with the naked eye

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.
