The formula vw=f⋅λ = ⋅ describes the relationship between the speed of a wave ( vw ), and its frequency ( f ) and wavelength ( λ).
This formula is commonly known as the wave equation. It states that the speed of a wave is equal to the product of its frequency and wavelength.
The speed of a wave refers to how fast it propagates through a medium. It can be thought of as the rate at which one wave cycle travels through a point in one second.
Frequency, on the other hand, refers to the number of wave cycles that pass through a point in one second. It is measured in hertz (Hz).
Wavelength is the distance between corresponding points on two consecutive wave cycles. It is typically measured in meters (m) or other units of length.
By multiplying the frequency and wavelength together, we get the speed of the wave. This formula applies to all types of waves, including sound waves, light waves, and radio waves.
