Calculate the wavelength of 146 mhz?
The wavelength of a frequency is the propagation speed divided by the frequency. A wave of 146 MHz, with a propagation speed of 3x108 m/s (speed of light), has a wavelength of 3x108 divided by 146x106, or about 2 m.
Why a sine wave is a simple vertical line in a frequency domain?
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.
What is the relationship of the input frequency and output frequency in a FULL-wave rectifier?
The frequency of a full-wave rectifier is double that of the input, if the input is a sine wave or triangle wave. If the input is a square wave, the output is DC. If the input is a sawtooth wave, the output is a triangle wave of the same frequency.
What is the formula for wave speed with period included?
1/frequency of wave
If the input frequency to a full wave rectifier is 400Hz what is the ripple frequency?
twice the frequency that is rectified.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation
What is optimum frequency in wave propagation?
The optimum frequency in wave propagation refers to the frequency at which a wave can travel with minimal loss and attenuation over a given medium. This frequency allows for efficient transmission of the wave without excessive absorption or scattering in the medium. Determining the optimum frequency involves considerations such as the properties of the medium, the distance of propagation, and potential interference from other waves.
What is the significance of the omega symbol in the context of wave propagation?
The omega symbol is significant in wave propagation as it represents the angular frequency of a wave. It helps to describe the frequency and speed of the wave, which are important factors in understanding how waves travel through a medium.
How does the frequency of a sound wave affect the speed at which the sound wave moves?
The frequency of a sound wave does not affect the speed at which the wave moves. The speed of sound in a medium is determined by the properties of that medium, such as its density and elasticity. However, frequency does impact the pitch of the sound we hear.
How is a waves frequency related to a waves length?
Frequency and wavelength of a wave are inversely related: as frequency increases, wavelength decreases, and vice versa. This relationship is described by the wave equation: speed = frequency x wavelength. In other words, for a given wave speed, if frequency increases, wavelength must decrease to maintain the same speed.
What has the author James Frederick Ward written?
James Frederick Ward has written: 'National frequency standardization by high frequency radio propagation' -- subject(s): Charts, diagrams, Frequency standards, Ionospheric radio wave propagation
What is the relationship between the cosine function and the variables kx and wt in the context of wave propagation?
In wave propagation, the cosine function is used to represent the oscillatory behavior of waves. The variables kx and wt are related to the wave's spatial and temporal properties, respectively. Specifically, kx represents the wave's spatial frequency and wavelength, while wt represents the wave's angular frequency and period. The cosine function helps to describe how these variables interact to produce the wave's overall behavior as it propagates through space and time.
Which frequency levels does space propagation use?
Space propagation typically uses high frequency levels in the range of microwaves and radio waves to enable long-distance communication without the need for physical connections.
How are wavelenghth and frequency of electromagnetic radiation related?
For any wave, (wavelength) times (frequency) = (speed of propagation).For electromagnetic waves, (wavelength) times (frequency) = (speed of 'light')
What are the five properties of light and wave?
The five properties of light and waves are: wavelength (λ), frequency (ν), speed, amplitude, and direction of propagation. Wavelength is the distance between two peaks in a wave, frequency is the number of wave cycles per second, speed is determined by the medium through which the wave travels, amplitude is the height of a wave's peak, and direction of propagation is the path along which the wave travels.
How does the phase shift affect refraction in the context of wave propagation?
The phase shift affects refraction in wave propagation by changing the direction of the wave as it passes from one medium to another. This change in direction is caused by the difference in the speed of the wave in each medium, which leads to a change in the wavelength and frequency of the wave.
What happens to the frequency if the wavelength of the wave decreases?
Assuming the wave propagation speed remains constant, a decrease in wavelength corresponds to an increase in frequency. However there are cases (e.g. waves breaking on a beach) where the wave propagation speed is not constant, the situation gets much more complicated in those cases.
