Detailed explanation-1: -(d) Wave velocity: The distance travelled by a wave in one second is called its wave velocity. Its S.I. unit is metre per second (ms−1).
Detailed explanation-2: -Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.
Detailed explanation-3: -Answer: Wave velocity can be defined as the distance traveled by a wave in one second.
Detailed explanation-4: -Wave speed is defined as the speed at which a wave travels. It is related to wavelength, frequency and time period. It is given by the formula v = f, Where v is the velocity of the wave, f is the frequency of the wave, and is the wavelength.
Detailed explanation-5: -All electromagnetic waves have the same speed of 3 x 108 ms-1 in a vacuum. The Speed of electromagnetic waves is less when they travel in a medium. Light waves travel with a speed of 300, 000 kilometres per second in a vacuum.
