The formula for calculating wave speed is indeed derived from the relationship between frequency and wavelength. In physics, the speed of a wave can be expressed using the formula:

Wave Speed (v) = Frequency (f) × Wavelength (λ).

In this equation, frequency represents how many cycles of the wave pass a certain point in one second, measured in hertz (Hz), and wavelength is the distance between successive peaks (or troughs) of the wave, measured in meters (m). By multiplying these two quantities, you obtain the speed of the wave, which expresses how far the wave travels in a given amount of time.

The other options do not relate to wave speed. The second option involves mass and acceleration, which pertains to Newton's second law of motion rather than wave dynamics. The third option refers to force and distance, which concerns work or energy calculations. The fourth option involves mass and time in a way not relevant to wave speed, instead resembling equations of motion. Thus, the choice that correctly identifies wave speed is based on the fundamental properties of waves: frequency and wavelength.
