Answer:
A.The frequency formula in terms of time is given as: f = 1/T where, f is the frequency in hertz, and T is the time to complete one cycle in seconds. The frequency formula in terms of wavelength and wave speed is given as, f = /λ where, is the wave speed, and λ is the wavelength of the wave.
B.pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.
C.Speed = Wavelength x Frequency
