DOPPLER SHIFT Doppler is the apparent change in wavelength (or frequency) of an electromagnetic or acoustic wave when there is relative movement between the transmitter (or frequency source) and the receiver.

formation is on the shore but still close enough to the ocean that some of the water from the waves are able to advance past the larger rocks and surround the smaller rocks while the sides of the formation jet out into the water. The dark blue-green ocean water is crashing against the brown rocks causing the white waves to jet straight up in the air. There are white caps in the middle of the ocean and larger waves closer to shore displaying a rough and windy day. The sly is a royal blue

Isaac Newton (~1665) made up a particle model of light to explain many of the known behaviours

THIS FILE DOWNLOADED FROM THE IB NOTES SITE: http://ibnotes.tripod.com/ TOPIC 2— MECHANICS FOUNDATIONS: • • • Displacement— A measured distance in a given direction— tells us not only the distance of an object from a particular reference point‚ but also the direction from the reference point— is a vector. Velocity— Is speed in a given direction‚ and is also a vector. Acceleration— is the rate of change of velocity in a given direction (velocity/time). The unit in SI is metres per second

properties of a wave and a particle. Its wave-like properties are best shown in its propagation while the particle-like properties in the emission and absorption of light.[1] As light behaves like a wave‚ superposition is observed between interacting waves. Superposition of waves is the addition of waves that travel across the same medium. The resulting wave from this addition has amplitude at a particular point that is the algebraic sum of the amplitudes of its constituent waves.[3] This superposition

we need those things to get chilled. Everything were in place when the worst part happened. That Tidal wave or Tsunami came and ruin everyone’s happiness… To be honest‚ my face was like a combination of sadness and anger. It is because of how a large wave came and ruined every little thing. Those people who were so happy enjoying their vacation were left nothing but a very tragic place. Waves are crashing them until some people wouldn’t be able to survive that time. Thailand was once seen with

The wave model can be used to explain how current technologies transfer information * describe the energy transformations required in one of the following: mobile telephone‚ fax/ modem‚ radio and television Energy transmission in mobile telephone: sound wave energy (input sound) -> electrical (in transmitting phone) – > radio wave (transmit signal) -> electrical (in receiving phone) -> sound (output sound) * describe waves as a transfer of energy disturbance

today I am going to discuss how time changes someones sense of identity and shapes who we really are even from individual to group through a novel called ‘The Wave’ by Morton Rhue‚ a film called Two Hands directed by Gregor Jordan and a poem called There I Am by Liz Linn. The way identity is changed over time is supported in the novel The Wave by Morton Rhue through the themes such as individuality versus conformity‚ doctrinisation‚ peer pressure‚ justice for all and intimidation illustrated through
