λ Wavelength (λ) is the least distance between any two points in phase

Q. A mains transformer vibrates the floor at 50Hz. 360 o = 2 Π radians Q. A mains transformer vibrates the floor at 50Hz. What is the time for a complete cycle?

Wave speed equation speed = distance time

Wave speed equation

λ B A d λ Wavelength (λ) is the least distance between any two points in phase B A Phase difference between particles at A and B = 2 Π d radians λ d Phase difference is the fraction of a cycle between two particles measured in radians or degrees.

λ B A d λ Wavelength (λ) is the least distance between any two points in phase B A Phase difference between particles at A and B = 2 Π d radians λ d 360 o = 2 Π radians Phase difference is the fraction of a cycle between two particles measured in radians or degrees.
