what is the relationship between frequency and aerial length?

The general rule is: the higher the frequency, the smaller the antenna. Students in RF usually start with the dipole antenna, which is half a wavelength in size. Making it longer will degrade its performance.

In a given medium under fixed conditions, vw is constant, so that there is a relationship between f and λ; the higher the frequency, the smaller the wavelength. ... Because they travel at the same speed in a given medium, low-frequency sounds must have a greater wavelength than high-frequency sounds.

There is a reciprocal relationship between frequency and the time for a cycle (the 'period'): frequency = 1 / clock period. clock period = 1 / frequency. For example, if a CPU operates at 100 Hz, its "clock cycle" is 0.01 second = 10 ms; if it operates at 100 MHz, its clock cycle is 0.000 000 01 second = 10 ns.

So increasing the frequency 7x while leaving the displacement the same results in increasing the velocity at which the bearing must move by 7x. The point here is simple. There is a direct relationship between the frequency, the displacement and the velocity.

Frequency and wavelength are inversely related. The longer the wavelength, the lower the frequency. Thus, wave B is 3 times the frequency of Wave A and wave C is 4 times the frequency of wave A.

What is the relation between the amplitude and the frequency of a wave? ... The amplitude and the frequency of a wave are equal. The amplitude decreases with an increase in the frequency of a wave. The amplitude increases with an increase in the frequency of a wave.

Angular frequency (ω), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second. Hence, 1 Hz ≈ 6.28 rad/sec. Since 2π radians = 360°, 1 radian ≈ 57.3°.

Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related: Speed = Wavelength x Wave Frequency.

Frequency defines the total number of occurrence of oscillations in a unit time. While wavelength is defined as the length of a wave. Frequency measures the time whereas wavelength measures the distance. Hertz is the measuring unit of frequency.

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength.

Pitch is related to frequency. ... Shorter prongs produce higher pitch (frequency) sounds than longer prongs. Long prongs will bend more readily and therefore tend to vibrate at a lower frequency when struck. Volume, or loudness, is related to the strength, intensity, pressure, or power of the sound.

The relationship between pitch and frequency. The pitch of a sound you hear depends on the frequency of the sound wave. A high frequency sound wave has a high pitch, and a low frequency sound wave has a low pitch.

Wavelength is also measured in metres ( ) - it is a length after all. The frequency ( ) of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz ( ), since one hertz is equal to one wave per second.

The wavelength of any wave with a constant speed is inversely proportional to its frequency, because as something vibrates more frequently, there is less time between one vibration and the next. Each complete vibration is one wavelength, so if there is less time, it can only go a shorter distance.

The broadcasting frequencies used by TV aerials, FM and DAB radio are all different. ... This means that the aerial type that you would typically use for TV and radio reception would be different and the higher the frequency, the shorter the wavelength and element size that would be required on the antenna themselves.

Dipole length formula Often a formula for the length of a dipole in feet is seen as 468 / frequency. This can be derived by taking the figure of 492 seen in the formula above and multiplying it by the typical A or end effect factor of 0.95.

Wave speed is related to both wavelength and wave frequency. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time.
