Final answer:
The speed of the wave with a frequency of 8Hz and a wavelength of 5m is 40 meters per second, is 40 m/s.
Step-by-step explanation:
To determine the speed of a wave when the frequency is given, we use the formula:
v = λ × f,
The student has asked about the speed of a wave when given the frequency and wavelength. The formula to calculate the speed (v) of a wave is given by the product of its frequency (f) and wavelength (λ), this is expressed as
v = f * λ.
To answer the question, we'll multiply the given frequency of 8Hz (8 cycles per second) by the given wavelength of 5m (meters). So the calculation will be as follows:
v = 8Hz * 5m = 40 m/s.
Therefore, the speed of the wave is 40 meters per second.
As the given question is incomplete, the complete question is:
What is the speed of this wave if the frequency = 8Hz and the wavelength is 5m?
