# Science Project on “Waves of Energy”, Project Experiment Topics on Energy in Different Forms for Class 8, 9, 10 and 12 Students.

Waves of Energy

Materials Required:

1. Stiff paper
3. Pencils
4. Modelling clay
5. String
6. Scissors
7. Quart milk cartons

Just like waves break on the sea-shore, similarly energy waves, like sound waves and radio waves too flow in a similar way.

We all know that a wave rises and then falls. The part of the wave’s movement, where it reaches the highest point, is known as its “crest” and the lowest portion is known as the “trough”. The distance between the crest and the trough is measured as a “wavelength.”

One of the differences between a sea wave and an energy wave is that while a Tsunami wavelength can measure upto 100 miles, a 550 Hertz wavelength is merely 2 feet high.

Have you ever wondered, what a wave actually is? It is merely a force of energy, which makes the water rise and fall.

Go to a small lake in your neighbourhood and have a friend hold a piece of long rope across the water body. Hold the end of the rope and move it jerkily up and down quickly.

You will observe the rope taking the shape of a wave and will keep going down towards the other end of the rope. Your friend will suddenly find his end of the rope then yanked out of his hand.

You can also take a round cake pan and fill it half with water. This experiment will help you determine the center of the water container. Take a dropper and squeeze a drop of water into what you feel to be the centre of the water.

If you have found the spot correctly, then the waves caused by the droplet of water will ripple out to the edge of the pan and then come back to converge at the center.

If this does not happen, keep repeating the process till you find the exact center.

Sound waves can travel in many elements, besides air. For instance, if you place your ear at the end of a metal pipe and get someone else to make some sound at the other end of it, you will hear the sound travel to your end of the pipe.
