What is the meaning of v = fλ?

Answer

The equation v = fλ is the fundamental wave equation relating velocity (v), frequency (f), and wavelength (λ). It states that wave speed equals frequency multiplied by wavelength. This means waves with higher frequency must have shorter wavelengths if speed is constant, and vice versa. This relationship applies to all waves sound, light, water waves, and more. It's crucial for understanding wave behavior, designing antennas, analyzing spectra, and countless applications in physics and engineering.
