Key Concept Light Waves Interact With Materials-PDF Free Download

electromagnetic waves, like radio waves, microwaves, light, and x-rays are examples of transverse waves. Longitudinal waves travel through a medium in a direction parallel to the direction of travel of the wave. Mechanical waves such as sound waves, seismic waves created by earthquakes, and explosions are all examples of longitudinal waves.

Q: What are mechanical waves? A: Waves that require a medium in which to travel. A medium is the _ that waves travel through o Mediums can be solid, liquid, or gas Examples of mechanical waves include sound waves, seismic waves, ocean waves, etc Q: Describe two types of mechanical waves.

electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Visible light waves are the only electromagnetic waves we can see.

A wave a moving disturbance. (Sound, water waves, etc. make some material substance move as they go by. Electromagnetic waves, such as light or radio waves, make electric and magnetic fields change strength.) Transverse waves: The medium is displaced perpendicular to the direction of propagation. Examples: light, string waves, water waves .

Chapter 16 Waves and Sound 179 Chapter 16 WAVES AND SOUND PREVIEW A wave is a disturbance which causes a transfer of energy.Mechanical waves need a medium in which to travel, but electromagnetic waves do not. Waves can be transverse or longitudinal, depending on the direction of the vibration of the wave.Sound is a longitudinal

definition Q 1 ¼ 2αv ω is under the assumption of homogeneous waves, which will not be correct for inhomogeneous waves. Because of the high-level attenuation observed in near-surface formations and petroleum reservoirs, seismic waves are generally inhomogeneous. The P2-waves are much more highly attenuative than P1- or S-waves.

whereas the water waves move perpendicularly to the boat. 3. Answers may vary. Sample answer: Sound waves and shock waves are examples of longitudinal waves. In these waves, the disturbance travels along the same axis as the motion of the wave. 4. The "wave" is not a true mechanical wave because there is no equilibrium point in the motion.

2 Gerstner Waves Sine waves are simple, but they do not match the shape of real water waves. Big wind waves are realistically modeled by the Stokes wave function, but it's rather complex. Instead, Gernster waves are often used for realtime animation of water surfaces. Gerstner waves are named after František Josef Gerstner, who discovered them.

Some light is also reflected off the inside surface of the film. When the two reflected light waves meet, they may be in phase (the waves aligned peak to peak and trough to trough) or out of phase (not aligned). In phase light waves produce the same color as the incoming light (e.g., white light) making the

of λ. Thus, long waves travel faster than short waves. The study of wind waves is simplified by treating them as "small amplitude" waves. Small amplitude means that the wave steepness, which is ratio of wave height H to wavelength λ, is smaller than one twentieth, in idealized situations.

produce standing waves on its surface. These are called Faraday waves, first described by Michael Faraday in 1831. Faraday waves are still an active area of research today, more than 150 years after their initial discovery. In current research the terms "Faraday instability" and "standing gravity waves" are also used for this phenomenon.

Quantum Physics Particles act like waves! Particles (electrons, protons, nuclei, atoms, . . . ) interfere like classical waves, i.e., wave-like behavior Particles have only certain "allowed energies" like waves on a piano The Schrodinger equation for quantum waves describes it all. Quantum tunneling Particles can "tunnel" through walls!
