# Relationship between wavelength and period

## Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed Since speed is distance traveled / time spent, and a wave moves a distance of one wavelength in a time of one period, its speed must be: speed = distance / time.

The nature of a wave was discussed in Lesson 1 of this unit. In that lesson, it was mentioned that a wave is created in a slinky by the periodic and repeating vibration of the first coil of the slinky. This vibration creates a disturbance that moves through the slinky and transports energy from the first coil to the last coil. A single back-and-forth vibration of the first coil of a slinky introduces a pulse into the slinky. But the act of continually vibrating the first coil with a back-and-forth motion in periodic fashion introduces a wave into the slinky. Suppose that a hand holding the first coil of a slinky is moved back-and-forth two complete cycles in one second.

Wavelength and period are two different, but related properties of waves. The main difference between wavelength and period is that the.

In physics , the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. Wavelength is usually determined by considering the distance between consecutive corresponding points of the same phase , such as crests, troughs, or zero crossings and is a characteristic of both traveling waves and standing waves , as well as other spatial wave patterns. The term wavelength is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium for example, vacuum, air, or water that a wave travels through. Examples of wave-like phenomena are sound waves , light , water waves and periodic electrical signals in a conductor. A sound wave is a variation in air pressure , while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary.

Wave Period and Frequency

## Frequency Wavelength and Period

As was discussed in Lesson 1 , a wave is produced when a vibrating source periodically disturbs the first particle of a medium. This creates a wave pattern that begins to travel along the medium from particle to particle. The frequency at which each individual particle vibrates is equal to the frequency at which the source vibrates. Similarly, the period of vibration of each individual particle in the medium is equal to the period of vibration of the source. In one period, the source is able to displace the first particle upwards from rest, back to rest, downwards from rest, and finally back to rest.

You don't have to be a master at RF to be a good WiFi engineer. But you do need to understand the basics. Just as the name implies, "frequency", its something that happens over and over and over again. It is very frequent, consistent, and repetitive. One cycle, specified event, is measured 1 second in time which equals 1 Hz. As the CWNA mentioned, "alternating current is defined as a single change from up to down to up, or as a change from positive, to negative to positive". We are dealing with simple math - 1 and 5 cycles per second.

Wavelength and period are two different, but related properties of waves. Waves consist of oscillations. In order to transport a wiggle along the rope, each particle on the rope should move up and down. For instance, at the time shown on the diagram below, the particle at A is at the highest position peak of its up-down motion. This is the case for a particle at B. A particle at C would also be on its way up, a little faster than the particle at B it would slow down to the speed of B when it reaches that same level.
