What is the frequency of a sine wave is?
The frequency of a sine wave can be thought of in several different ways: -- watching the wave from one fixed point, the number of times the wave reaches its maximum amplitude in one second, or the number of complete waves that pass you in one second -- the speed of the wave, divided by the distance between two consecutive maximum points on it -- the reciprocal of the time it takes for one complete wave to pass you (' 1 ' divided by that length of time)
Conclusions of full-wave rectifier?
A half wave rectifier is not as effective as a full wave rectifier. With a 1/2 wave, you are throwing away one hump of the sine wave...either positive or negative portion. With a full wave rectifier you get both humps...either positive or negative. The resultant effective voltage is much greater with a full wave rectifier, because there is very little time when the voltage is zero. The half wave is zero for 1/2 of the cycle.
Why did they wave palms?
During that time waving and lying down palms was a sign that a king was coming.
How does fetch wave length wave height and period relate to an ocean wave?
Fetch refers to the distance over water that the wind blows in a single direction, influencing the energy and size of waves. Wave height is the vertical distance between the crest and trough of a wave, which increases with stronger winds and longer fetch. The wave period is the time it takes for two consecutive wave crests to pass a fixed point and is affected by both wind speed and fetch. Together, these factors determine the characteristics of ocean waves, affecting their power and how they interact with the coastline.
What is the fastest moving earthquake wave?
The P-wave which is a form of body wave known as a compression or longitudinal wave.
What does the conductor of an orchestra wave to keep in time?
He gives the tempo, but he also controls his musicians, tells them to be more expressive, louder, go faster etc.
When a em wave is incident normally on a perfect conductor then?
A perfect conductor will perfectly reflect an incident wave.
What does an orchestra director wave to keep time?
a baton
When a em wave is incident on a perfect conductor then what happens to the reflection coefficient?
When an electromagnetic wave is incident on a perfect conductor, all of the wave is reflected. This results in a reflection coefficient of +1, indicating that 100% of the wave is reflected back.
What does a conductor wave to direct his orchesta?
A baton
How do you sketch an half wave rectified current with amps and time?
Draw a sine wave, except that when it wants to go negative, keep it at zero instead.
Why TEM modes does not exist in wave guides?
Arif Ullah khan utman kheel this is because for conductor E parallel is zero this means that the surface of the wave guide is at equipotential and this potential follow the laplace equation .it means that there is no maxima and minima inside the wave guide . this means that the electric field inside zero . hence the TEM do not exist in wave guide only TE and TM can be exist . if we place some conductor in the wave guide then the conductor inside will not be equipotential and the TEM waves can be exist . like in Coaxial cables
What is required of the conductor in a classical music concert?
To wave a little stick and hope the orchestra actually pays attention to what s/he is doing. To teach them phrasing, to help keep them together. To see what the orchestra overlooks.
Is electric current a wave?
If the current is alternating, then it has the properties of a wave in the conductor, such as frequency, wavelength, amplitude, phase, group velocity etc.
Why is it impossible to increase the frequency and the the wave length of a wave at the same time?
v = w*f. If w (wave length) is increased f (frequency) must go down to keep v (velocity) constant.
What does a conductor do?
A conductor is the person who guides the band/orchestra in tempo, style, and many other factors that make music. Often times, he will use a baton or his hands and wave them in the air to keep tempo and stress some parts of the music. A conductor is also the person on a train, streetcar, or other public transport system who takes fares and sells tickets. A conductor is also a substance or medium that can conduct light, heat, electricity, or sound.
