Medium frequency (MF) waves are electromagnetic waves that fall within the frequency range of approximately 300 kHz to 3 MHz. They are used for radio broadcasting, air traffic control, and maritime communication due to their ability to travel long distances during the day and even further at night by reflecting off the ionosphere. MF waves have properties that make them suitable for both ground-based and skywave communication applications.
What else can I help you with?
In a given medium as the frequency of a wave increases its speed does what?
In a given medium, as the frequency of a wave increases, the speed of the wave remains constant. The speed of a wave in a medium is determined by the properties of that medium, such as its density and elasticity, and is independent of the frequency of the wave.
Is it true or false that the greater the frequency of the wave in a particular medium the greater the speed of the medium.?
False. The speed of a wave in a medium is determined by the properties of the medium itself, such as its density and elasticity, rather than the frequency of the wave. The frequency of a wave only affects its wavelength and energy, not the speed of the medium.
What is the lowest natural frequency of a standing wave?
The lowest natural frequency of a standing wave is the fundamental frequency, which is determined by the length of the medium the wave is traveling through. It is inversely proportional to the length of the medium and is the frequency at which the medium vibrates with the greatest amplitude.
The speed at which a wave travels through a medium is called what?
The speed at which a wave travels through a medium is called the wave speed or wave velocity. It is determined by the properties of the medium, such as its density and elasticity, and is independent of the wavelength and frequency of the wave.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
Yes, the frequency of a wave remains constant as long as the medium temperature and pressure do not change. Temperature and pressure affect the speed of sound in a medium, not the frequency of the wave.

Does varying the either the wavelength or frequency affect the speed of the wave in that medium?
No, varying the wavelength or frequency does not affect the speed of a wave in a particular medium. The speed of a wave in a medium is determined by the properties of that medium, such as its density and elasticity. Changing the frequency or wavelength only affects other characteristics of the wave, such as its energy or pitch.
When a wave travels from a denser medium to a less dense medium what happens to its frequency?
The frequency of the wave remains the same when it travels from a denser to a less dense medium. However, the wave will change its speed and wavelength.
How can you change the frequency of a wave?
The frequency of a wave can be changed by altering the speed of the wave's source or by changing the medium through which the wave is traveling.
What will change the velocity of a periodic wave?
The velocity of a periodic wave is determined by the medium through which it travels and the frequency of the wave. Changes in the medium's properties (such as density or elasticity) can alter the wave velocity. Additionally, changes in the frequency of the wave can affect its velocity according to the wave equation.
What is the relationship between the frequency and wave medium?
There's no relationship between the frequency and the medium. The frequency of a wave is determined by the source. Once the wave leaves the source and sets out on its journey, the frequency doesn't change, regardless of what kind of stuff the wave encounters and has to travel through.
What are the factors that affect the wavelength?
The factors that affect the wavelength of a wave include the medium through which the wave is traveling, the frequency of the wave, and the speed of the wave in that medium. In general, wavelength is inversely proportional to frequency, meaning that as frequency increases, wavelength decreases.
Which wave characteristics remain unchanged when a wave crosses a boundary into a different medium?
The frequency of the light remains unchanged as it depends on the source of the light rather than the medium its traveling in.
