Energy's Transformation:
There are many types of different kinds of energy for example (Light energy, sound energy, kinetic energy etc...) Energy is measured in Joules (J) Energy cannot be seen or touched but we can observe the effects it has on objects.
Energy cannot be created nor destroyed. Energy can transform into another substance of energy, energy that has been transformed is called (Law of Conservation of Energy) Energy transformations is all the change that happen around you. For Example when you have a device the potential energy in the battery is turned into electrical energy. Electrical energy: ( Energy that is then turned into light energy for the screen and the sound energy for the speaker.
Wasted Energy:
Sometimes energy is wasted e.g when energy is transformed from one kind to another, some of the initial energy is transferred to a form which isn't useful or even wanted. Think about a light bulb, after a period of time it is hot. Which means some of the electrical energy has been transformed into heat and the energy transfer is Electrical energy-Light energy-Heat energy.
What is a Wave?
There are two types of waves Transverse and longitudinal these waves a very different to each other. Longitudinal waves cannot be seen, these waves vibrate parallel to the direction they are heading too. These waves stretch out and you can hear these waves another name for it is called a sound wave. Transverse ways are ways you can see like the waves in the ocean, they travel up at a 90' to the direction they are travelling. These are two examples of a transverse wave 1. Light waves 2. Ocean waves these waves are the best example of a transverse wave.
Measuring waves:
Amplitude, Wavelength, and Frequency are three types of measuring waves.
For starters amplitude is the height of the crest or trough of a wave when measured from the rest position. Wavelength is the maximum distance between two crests or troughs.Frequency is the number of waves that pass a point in one second. Measured in Hertz (HZ).
