The formula for calculating the velocity of waves is v = λf, where v is the velocity, λ is the wavelength, and f is the frequency.
The wavelength of a wave can be measured by taking the distance between two consecutive peaks or troughs of the wave.
Yes, the velocity of waves can change depending on the medium they are traveling through. For example, the velocity of sound waves is faster in solids than in gases.
The velocity of waves can be affected by the properties of the medium, such as density and elasticity. It can also be affected by the temperature and pressure of the medium.
The velocity of waves is used in many practical applications, such as calculating the speed of sound in air for aviation and designing earthquake-resistant buildings. It is also used in fields like oceanography and seismology to study and understand the behavior of waves in different mediums.
