Answer:
The wave speed (v) of a wave can be calculated by multiplying its frequency (f) by its wavelength (λ). Mathematically, we can express this as:
v = f x λ
Substituting the given values of frequency and wavelength into this formula, we get:
v = 500 Hz x 0.40 m
Multiplying these values, we get:
v = 200 m/s
Therefore, the wave speed of a wave that has a frequency of 500 Hz and a wavelength of 0.40 m is 200 m/s.
