Explanation:
Detailed explanation-1: -WAVE SPEED FORMULA. Wave speed equation (Speed = Wavelength x Frequency) relates wave speed to wavelength and frequency. When the wavelength and frequency are known, this equation can be used to calculate wave speed. Wave frequency is the number of waves that move per second.
Detailed explanation-2: -To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x, t)=Asin(kx−t+). The amplitude can be read straight from the equation and is equal to A. The period of the wave can be derived from the angular frequency (T=2).
