Unit 5 Cc Flashcards
6.2 Pendulum Exploration
Unit 7 chapter 19
The effects of amplitude, length, and mass on period were investigated.
Ka pendulum concepts
Molly Ayres box1A block1
A period is the time for one cycle its formula is period equals one divided by frequency
A frequency is the number of cycles per unit of time it’s formula is frequency equals one divided by period
6.1 Pendulums Unit 7 chapter 19 A Pendulum is when a mass is suspended from a fixed point as to move to and fro by the action of gravity Ka pendulum concepts

The force that moves a pendulum is Gravity this is in a downwards direction but this is not the direction in which it moves. The other force acting on the pendulum is tension. The bob on a pendulum is fastest at the top of a swing and slowest at the bottom. The Bob keeps moving due to inertia.the length affects an. Pendulums period.
6.3 Frequency & Period Unit7 chapter19 Frequency is the number of cycles per second. Period is the time for one cycle. Textbook unit 19 Molly Ayres block One box1a
Period and frequency are used to describe waves, pendulums, and various other paths of matter in science they are opposites off each other
A period is the time for one cycle its formula is period equals one divided by frequency
A frequency is the number of cycles per unit of time it’s formula is frequency equals one divided by period
6.4 Wave Types and Terminology
Unit 7 chapter19
Waves are either transverse or longitudinal.
Waves have frequency, wavelength, and amplitude.

- Transverse wave: A wave with vibration at right angles to the direction the wave is traveling. Light consists of transverse waves.
- Longitudinal wave: A wave in which the individual particles of a medium vibrate back and forth along (parallel to) the direction in which the wave travels—for example, sound.
6.5 Properties of waves Chapter19 unit7 All waves exhibit reflection, refraction, diffraction, and interference. Chapter19 textbook Molly ayres box1a
Reflection:The return of light rays from a surface in such a way that the angle at which a given ray is returned is equal to the angle at which it strikes the surface. When the reflecting surface is irregular, the light is returned in irregular directions; this is diffuse reflection. In general, the bouncing back of a particle or wave that strikes the boundary between two media.
Refraction: The bending of an oblique ray of light when it passes from one transparent medium to another. This is caused by a difference in the speed of light in the transparent media. In general, the change in direction of a wave as it crosses the boundary between two media in which the wave travels at different speeds.
Defection:The bending of light that passes around an obstacle or through a narrow slit, causing the light to spread and to produce light and dark fringes.
Interference:The result of superposing different waves, often of the same wavelength. Constructive interference results from crest-to-crest reinforcement; destructive interference results from crest-to-trough cancellation. The interference of selected wavelengths of light produces colors known as interference colors. See also constructive interference, destructive interference, interference pattern, and standing wave.
6.6 Mathematics of waves
Chapter19 unit7
Period and frequency are related T = 1/f f = 1/T
Speed, wavelength, and frequency are related with v=lambda times f
Chapter19 textbook
Molly Ayres box1a
The unit for frequency is hertz
Wave speed equals frequency times wave length
6.7 Slinky Lab
Reflection, Refraction, Diffraction, and Interference were investigated.
I was gone and just made up the lab this morning I will turn it in next class
6.8 Standing Waves Unit6 chapter 19 When a reflected wave interferes with oncoming waves at a particular frequency, a standing wave forms. Book chapter 19 Molly Ayres box1a
The stationary wave pattern formed in a medium when two sets of identical waves pass through the medium in opposite directions. The wave appears not to be traveling. The result of wave interference.

6.9 Doppler Effect Unit 6 chapter 17 The Doppler effect is exhibited when a sound source is moving toward or away from an observer. Molly Ayres box1a block 1
