Forces: If a Force is applied to a body, it will cause that body to move. A body that is already moving will change its speed or direction. Note that the term 'change its spe
The points where amplitude is minimized are called as nodes.
Explain the Electromagnetic Induction The force exerted on an electric charge moving in a magnetic field leads to the idea of magnets being able to produce electricity as well
The waves which needs medium for their propagation are known as mechanical waves. Example : Waves on string and spring, waves on water surface, sound waves, seismic waves.
