AM waves have a wavelength of approximately 100 meters. FM waves have a wavelength of approximately 1 meter. Which one has a higher frequency? Which one has higher energy?(1 point)
To determine which type of wave, AM (Amplitude Modulation) or FM (Frequency Modulation), has a higher frequency and higher energy, we need to understand the relationship between wavelength, frequency, and energy.
The relationship between wavelength and frequency can be described by the equation:
Velocity = Wavelength x Frequency
From this equation, we can deduce that as the wavelength decreases, the frequency increases, and vice versa. This means that waves with shorter wavelengths have higher frequencies.
Now, let's compare the wavelengths given in the question. AM waves have a wavelength of approximately 100 meters, while FM waves have a wavelength of approximately 1 meter. Since the FM wave has a shorter wavelength, it corresponds to a higher frequency than the AM wave.
Therefore, FM waves have a higher frequency than AM waves.
Now, let's discuss the concept of energy in waves. The energy of a wave is directly proportional to its frequency. Higher frequency waves carry more energy.
Applying this principle, since FM waves have higher frequencies than AM waves, they also have higher energy.
In summary:
- FM waves have a higher frequency than AM waves.
- FM waves have higher energy than AM waves.
To determine which wave has a higher frequency, we can use the equation:
frequency = speed of light / wavelength
Given that the wavelength of AM waves is 100 meters and the wavelength of FM waves is 1 meter, we can compare their frequencies.
For AM waves:
frequency = speed of light / 100 meters
For FM waves:
frequency = speed of light / 1 meter
Since the speed of light is constant, and the wavelength in the denominator is smaller for FM waves, it indicates that FM waves have a higher frequency compared to AM waves.
Regarding which wave has higher energy, the energy of a wave is directly proportional to its frequency. Hence, since FM waves have a higher frequency, they also have higher energy compared to AM waves.
