Find the speed of a wave with wavelength 450 nm and frequency 45 Hz. The speed of a tsunami may be estimated by the following equation speed g d where g 2is the acceleration due to gravity g 981 meterssecond and d is the water. The frequency of the light wave is 5 times 1014 Hz.
Wave speed v is measured in metres per second ms frequency f.
This equation can be used to calculate wave speed when wavelength and frequency are known. Try a smart search to find answers to similar questions. Therefore the frequency of the light wave is 42 1014 Hz. The speed of a sound wave refers to how fast a sound wave is passed from particle to particle through a medium.
