Question

the wavelenght of a wave is 0.5 meters,and its period is 2 seconds .what is the speed of this wave?

Answer 1

Speed = Wavelength x Frequency

and frequency = 1/Period

Speed = Wavelength/Period

Speed = .5 * 2

Speed = 1 m/s

Answer 2

The distance at which the wave repeats itself is called the wavelength. The speed of a 0.5-meter wave is 0.25 m/s.

What is speed?

The speed of the wave is the ratio of the wavelength and the period. The period of the wave is given by the frequency.

Speed = Wavelength x Frequency = Wavelength ÷ Period

Given,

Wavelength = 0.5 m

Time = 2 seconds

Substituting values above:

Speed = 0.5 ÷ 2

= 0.25 m/s

Therefore, 0.25 m/s is the speed of the wave.
