which equation should be used to calculate the speed of a wave?\no speed = frequency x wavelength\no speed = frequency x hertz\no speed = period x wavelength\no speed = period x hertz
Answer
Brief Explanations:
The speed of a wave is calculated by multiplying its frequency and wavelength. Hertz is the unit of frequency, and period is the reciprocal of frequency. The correct formula is speed = frequency × wavelength.
Answer:
speed = frequency x wavelength
