# how are these two equations related? watch

1. how are these two equations related

1) frequency = 1/t
2) wave speed = d/t

thanks
2. Wavelength (lambda) = v/f ?

Wave speed =distance/time
=wavelength/time taken for one oscillation
Frequency, f, is the number of oscillations per second and the time period, T, is the time taken for one oscillation. Frequency is the inverse of the time period and vice versa.

Therefore
Wave speed=wavelength/ Time period
since time period is the inverse of frequency an so is equal to 1/f,
Wave speed =wavelength/ (1/f)
Wave speed =wavelength X frequency
