Waves and vibrations are disturbances that travel through a medium, such as air or water, and carry energy from one place to another.
Examples of waves and vibrations include sound waves, water waves, seismic waves, and electromagnetic waves (such as light).
While both waves and vibrations involve the transfer of energy, vibrations typically refer to repetitive back-and-forth motions of an object, while waves refer to the propagation of energy through a medium.
The speed of a wave depends on the properties of the medium it is traveling through, such as density and elasticity. It also depends on the wavelength and frequency of the wave.
There are several resources available online for practicing problems related to waves and vibrations, including textbooks, worksheets, and interactive simulations. Additionally, many educational websites offer practice quizzes and tests on this topic.
