How do you make a wave with a slinky?

With one hand, “pop” one end of the slinky with a single, quick, longitudinal shove to create a pulse wave, and watch the pulse travel down the length of the slinky. You can increase (or decrease) the speed of the pulse by changing the tension in the slinky (lengthening or shortening the slinky).

How does a slinky represent waves?

Notice that a wave travels along the slinky. This wave is a wave of motion back and forth along the slinky which travels along the slinky, because the back and forth motion is in the same line as the direction of motion this is called a longitudinal wave.

How would you show a high frequency wave with a slinky?

If you think about the slinky is the air particles. And my moving hand is the vibrating object you can see the high pressure push move through the slinky when my hand moves.

How do you find the wavelength of a slinky?

This is another very factions. So distance from two successes rarefaction is also the wavelength.

How does a slinky work physics?

As the slinky moves down the steps, energy is transferred along its length in a longitudinal or compressional wave, which resembles a sound wave that travels through a substance by transferring a pulse of energy to the next molecule. How quickly the wave moves depends on the spring constant and the mass of the metal.

How do you change the speed of a slinky wave?

On the number of coils the slinky has the more coils the slower the wave speed.

What is slinky in physics?

Slinky is a helical spring toy. By fixing one end on a rigid support and holding the other end waves can be generated. By moving it back and forth, longitudinal waves can be generated. By moving up and down, transverse can be made. Was this answer helpful?

What types of waves can you demonstrate with a slinky?

A slinky can easily demonstrate the two basic types of waves, longitudinal and transverse. In a longitudinal wave the particles move parallel to the direction the wave is moving. In a transverse wave the particles move at right angles to the direction of wave travel.

What type of wave does a slinky make?

A slinky can easily demonstrate the two basic types of waves, longitudinal and transverse. In a longitudinal wave the particles move parallel to the direction the wave is moving. In a transverse wave the particles move at right angles to the direction of wave travel.

What is frequency in a slinky?

Both of these patterns of motion have the fundamental frequency of oscillation, the lowest frequency of motion for a Slinky held at both ends—close to 1 hertz.

What law of motion is a slinky?

Slinkies gets their “walking” ability from two properties: wave motions and Newton's laws. When a Slinky sits atop a staircase, gravity acts on the toy, keeping it still. Knock over the Slinky, and Newton's second law comes into play.

What force is used on a slinky?

the gravitational force From the whole slinky point of view, there is only one force on the slinky - the gravitational force. This means that it falls and accelerates downward with an acceleration of -9.8 m/s2 just like all free-falling objects.

How do you increase tension in a slinky?

By stretching it further you have increased the tension and decreased the number of turns per unit length. Thus effective increased and effective decreased.

What type of energy is stored in a slinky?

If the bottom of the slinky is hanging freely, the kinetic energy of the compression wave transfers to spring potential energy as the slinky extends further downward. The spring potential energy is then converted back into kinetic energy as the slinky bounces upwards.

Do slinky waves have energy?

The video shows a hand making longitudinal and transverse waves on a slinky. Consider the transverse wave on a slinky. Any given part of the slinky is moving up and down, but the wave is travelling along the slinky. Energy also travels along the slinky.

What is the energy transfer in a slinky?

If the bottom of the slinky is hanging freely, the kinetic energy of the compression wave transfers to spring potential energy as the slinky extends further downward. The spring potential energy is then converted back into kinetic energy as the slinky bounces upwards.

Why does a slinky not fall?

A slow motion video shows that the bottom end stays stationary while the top moves towards it. As they meet the collapsed slinky then moves towards the ground. This happens because the bottom end has balanced forces acting upon it (gravity pulling it down and tension in the spring pulling it up).

How is a slinky elastic energy?

Likewise if a Slinky is stretched and let go, it will pull itself back to its original shape, that means that there's potential for energy in the Slinky's shape. This is another form of potential energy called elastic potential energy.

What are 3 interesting facts about the Slinky?

Slinkys were first sold at Gimbel's Department Store for the 1945 Christmas season. In 1948, they opened a factory to build the Slinky toy. More than 250 million Slinkys have been sold. The Slinky jingle: "It's Slinky, it's Slinky, for fun it's a wonderful toy.
