Physics waves

GCSE Physics: Waves

Wavelength can be a useful concept even if the wave is not periodic in space. Consider the presence of a wave in a slinky.

Introduction to waves

But it's a fairly abstract notion where we talk about a wave, we're really just pointing to a disturbance that's moving, usually along a medium, at least when we visualize it, but not always.

The particle might be moved upwards or downwards, forwards or backwards; but once moved, it is returned to its original equilibrium or rest position.

What is a Wave?

This is, of course, just one factor in the design of a violin. Mechanical Waves and Electromagnetic Waves All waves can be categorized as either mechanical or electromagnetic. In this example, a bat is used to transport energy from the player to the softball. So a wave is a disturbance propagating through space.

For any real-world system, however, the higher frequency standing waves are difficult if not impossible to produce. In 2B the wave of "evaporation" has moved away from the wreck site, and in 2C and 2D it is far from the wreck.

And I could let go of the rope. The height of the crest from the undisturbed water position or the depth of the trough from the undisturbed water position is the amplitude of the wave.

So, one cycle per second is one Hertz, as in: A traffic jam with no cause. So this right here is a sound wave. The gull or duck always returns to its original position.

Standing Waves

The approach is similar to that of applied mathematics. They are like sand ripples and sand dunes, and they just build up for no clear reason.

Maybe it spun out on ice. In a similar manner, a wave medium is the substance that carries a wave or disturbance from one location to another. You can think of the wave moving left to right, while the disturbance moves up and down. Put a little bit of energy in at the right rate and watch it accumulate into something with a lot of energy.

The sand grains bounce away from the lively antinodes and accumulate at the relatively quiet nodes. This ability to amplify a wave of one particular frequency over those of any other frequency has numerous applications.

If I look at the rope at some future period in time, maybe not that far down, the rope will look something like this. Basically, all non-digital musical instruments work directly on this principle. Vibrations and waves are everywhere.

If you take any system and disturb it from a stable equilibrium, the resultant motion will be waves and vibrations. Think of a guitar string—pluck the string, and it vibrates. The sound waves generated make their way to our ears, and we hear the string’s sound. Our eyes see what’s happening because they receive the electromagnetic waves.

Summary. Properties A wave is a disturbance that propagates through a medium. verb propogate; noun propogation refers to the transmission of a disturbance from one location to another.; sing. medium plu.

media refers to the intervening substance(s) through which a disturbance is transmitted.; Waves transfer energy, momentum, and information, but not mass. PHYSICS HELP.

A variety of question-and-answer pages which target specific concepts and skills. Topics range from the graphical analysis of motion and drawing free body diagrams to a discussion of vectors and vector addition.

I first discovered standing waves (or I first remember seeing them) while playing around with a phone cord. If you shake the phone cord in just the right manner it's possible to make a wave that appears to stand still. The world is awash with sound waves, they are all around us. However sound is so much more than simply a soundtrack to our lives, and the more we’ve discovered about the physics of sound, the more extraordinary the secrets it has revealed.

Louis de Broglie's Incorrect Interpretation of the Standing waves as the wave-Like Motion of a Particle in Orbit () InNiels Bohr had developed a simple (though only partly correct) model for the hydrogen atom that assumed; i) That the electron particle moves in circular orbits about the proton particle.
