A wave on a string is represented by the function y(x, t) = 0.05 sin(4x - 8t). What are the wavelength and the speed of the wave?
💡 Hint: Use the formulas for wavelength and wave speed.
Consider a sound wave in air characterized by a frequency of 500 Hz. Calculate the wavelength if the speed of sound at that temperature is 340 m/s.
💡 Hint: Remember the fundamental wave equation!
