As the frequency of a signal increases, its wavelength decreases. This is because the speed of propagation of the signal remains constant in a given medium, so as the frequency increases (more cycles per second), each cycle has less distance to cover, resulting in a shorter wavelength.

What is the wave length of mobile?
The wavelength of mobile phone signals typically falls in the range of 10 centimeters to 1 meter, depending on the specific frequency band being used by the mobile network.
What is an RF subsystem?
An RF (radio frequency) subsystem is a segment of an electronic system that is dedicated to handling radio frequency signals. It typically includes components such as RF amplifiers, filters, and mixers that are used to process and manipulate RF signals within a larger electronic system. RF subsystems are commonly used in communication devices, radar systems, and other applications that involve transmitting or receiving radio frequency signals.
When rf signals move around an object in their paths what is the phenomenon called?
The phenomenon is called diffraction, where RF signals bend and spread out as they encounter obstacles in their path, such as buildings or walls. This can result in signal weakening or distortions in communication systems.
Can gps signals travel underwater?
No, GPS signals cannot travel through water. Water is an effective barrier for GPS signals, causing them to weaken and lose accuracy when trying to penetrate underwater. GPS signals are designed to travel through the atmosphere, not through water.
Why L1 is chosen 1575.42MHz for GPS signal?
The L1 frequency of 1575.42 MHz was chosen as it offers a good balance between propagation characteristics and system complexity for GPS signals. This frequency is commonly used for civilian GPS applications due to its ability to penetrate atmospheric conditions and obstacles while still providing accurate positioning information. Additionally, this frequency was designated for civilian use to differentiate it from the military L1 frequency.
What happens if frequency increases?
If frequency increases, the number of occurrences of a cycle within a unit of time increases. This means that the signal changes more rapidly and the wavelength decreases. Higher frequency signals typically have higher energy and can carry more information, such as in the case of radio waves or light.
What happens when frequency increases?
When frequency increases, the number of occurrences of a repeating event within a fixed time interval also increases. In the context of sound waves, higher frequency corresponds to a higher pitch. In electronics, higher frequency signals can carry more data but may be more susceptible to interference.
What is the difference between red light and green light?
Red light has a longer wavelength and lower frequency compared to green light, which has a shorter wavelength and higher frequency. In terms of traffic signals, red light signals drivers to stop, while green light signals drivers to go.
What is the formula for finding the frequency of a wave?
The wavelength of a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as well as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).
Which of the three multiplexing techniques are used to combine analog signals?
Frequency-division multiplexing and wavelength-division multiplexing
A low energy electromagnetic wave would also have?
the lowest frequency Lester was here
If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
How radio communicate works?
Radio communication works on radio signals that are "beamed" into the air on a certain frequency. Frequency is a certain wavelength or band. The receiving equipment has to be set to receive the signal on the same frequency.
AM radio signals are broadcast at frequencies between 550 kHz and 1600 kHz and travel 2.99792 x 108 ms What is the shortest AM wavelength?
The shortest AM radio wavelength occurs at the highest frequency in the given range, which is 1600 kHz. To find the wavelength, we can use the formula: wavelength (in meters) = speed of light / frequency. So, the shortest AM wavelength is approximately 187.37 meters.
What is the wavelength of mobilephone?
The wavelength of mobile phone signals typically falls within the range of 10 centimeters to 1 meter, depending on the specific frequency band used by the mobile network provider.
What is a wave with the longest wavelength and lowest frequency?
The type of wave with the longest wavelength and lowest frequency is a radio wave. These waves have frequencies ranging from about 3 kHz to 300 GHz and are used for various forms of communication, including radio broadcasts and mobile phone signals.
Which of the three multiplexing techniques arre used to combine digital signals?
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
