Wave Lengths

QuestionAnswer
Waves oscillations that carry energy
Oscillation an up and down or back and forth motion
Vacuum space that has no matter in it
Mechanical Waves made by another force like a boat engine
Types of Mechanical Waves longitud and laditud waves
Electromagnetic Waves they are waves that do not need to travel in matter they can travel in a vacuum
Types of Electromagnetic Waves light waves or radio waves
Wave Properties four main characteristics of a wave
Amplitude one half the distance between a waves high point and low point
Crest a waves high point
Trough a waves low point
Resting Point middle between high and low point
Wavelength and symbol measure from a point on one wave to the same point on the next
Wavelength Units Frequency or Hertz HZ
3 Ways to measure wavelength are Wave
Frequency measurement of wave lengths in HZ
Units for Frequency Hertz HZ
Wave Speed how up and down a wave is if it goes up and down like 10 times in 10 seconds it higher HZ
Wave Speed Units Hertz
Wave Speed Equation v=f x λ
Medium middle point of a wavelength
Reflection light bouncing back or off a surface
law of reflection law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane
Reflected Ray A ray of light or other form of radiant energy which is thrown back
Incident Ray a ray of light that strikes a surface
Refraction waves being deflected in passing obliquely through the interface between one medium and another
Diffraction bending of waves around a barrier
Interference result of waves colliding into each other
Constructive Interference when waves combine an form a larger wave
Destructive Interference when waves collide and cancelled each other
Absorption when waves go through a substance and get absorbed
Absorbed colors the tendency of an object to absorb some frequencies of light
Reflected Colors the color that is absorbed vs released
Electromagnetic electric currents or fields
Spectrum the wavelengths and frequency range of electromagnetic waves
Visible Light Spectrum the segment of the electromagnetic spectrum that the human eye can view
Longitudinal Wave a wave vibrating in one direction getting larger
Expansion getting larger
Compression being squished down or made smaller
Intensity measurable amount of a property
Units of Sound decibels
Pitch rate of vibrations
Digital Signal an electrical signal that is converted into a pattern of bits

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.
