What frequency are ultrasonic waves?
Ultrasonic waves have a frequency range above the audible limit of human hearing, typically between 20 kHz and 100 kHz.
What wave has a shorter wavelength AM or FM?
Generally, the wavelength of an FM signal is shorter than an AM signal. A typical FM broadcast band is 88-108 MHz, while a typical AM broadcast band is 540-1660 KHz, making the FM signal wavelength 100 times shorter.
Can a high frequency carrier wave travel longer distance than low frequency carrier wave?
High frequency radio waves over ~100 MHz will usually travel only in a straight line - hence these applications are called 'line of sight'. Waves of lower frequency, say 500KHz to 30MHz (rough values only) are bounced off the ionosphere and can travel round the world. Waves of very low frequency, 10 KHz to 20KHz, can penetrate sea water, and are used to communicate with subs. But they are of such low frequency that they can carry no effective modulation other than ON or OFF. But they can do a job that nothing else can do.
If a wave has a frequency of 5.0 waves per second and the distance between the peaks of the wave is 20 cm. What is the speed of the wave?
wave velocity = frequency in Hz x wavelength in meterSo frequency = 5 Hz and wavelength = distance between successive peaks = 20 cm = 20/100 mHence wave velocity = 5 * 20/100 = 1 m/s
What is the history of gamma waves?
Gamma waves were discovered by a German neuroscientist in the 1960s and are a type of brain wave associated with cognitive functions such as attention, memory, and problem-solving. They are high-frequency brain waves, ranging from 30-100 Hz, and are believed to play a role in coordinating communication between different parts of the brain.
How are sound waves converted into radio waves?
Sound waves would not ordinarily be converted INTO radio waves.Sound Waves can be used to modulate the radio waves.The radio frequency of a typical FM station is around 100MHz.The audio is used to vary the FM frequency by the range of audio waves, perhaps 100 Hz up to 12 kHz. So the 100MHz signal varies from 100 MHz ± (100 to 12kHz)
How far apart are two typical stars?

What frequency are ultrasonic waves?
Ultrasonic waves have a frequency range above the audible limit of human hearing, typically between 20 kHz and 100 kHz.
Which type of EM waves has the longest wavelenght?
Extremely low frequency (ELF) waves have wavelength of the order of 100 megametres ( = 100,000 kilometres).
What determines energy in sound waves?
By the frequency. The higher the frequency, the shorter the wavelength. The lower the frequency the longer the wave length. C= L * f C = Time in milliseconds (343 m/s @ 20 degrees C , L= Wave Length or Lambda in meters and f= frequency in Hertz A little algebra and you have; L= C/f Example; 343 m/s / 100 Hz = .343 meters Frequency is a function of time, cycles per second. Time is the reciprocal of frequency (1/f= T).
What is the wavelength of radiation with a frequency of 3 million hertz and what region of the spectrum?
c = wavelength x frequency, where c = speed of light, which is 299,792,458m/sKnown: c and frequencyUnknown: wavelengthWavelength = c/frequency = (299,792,458m/s)/(3,000,000/s) = 99.9mIt is in the radio region of the electromagnetic spectrum.See the related link below.
What wave has a shorter wavelength AM or FM?
Generally, the wavelength of an FM signal is shorter than an AM signal. A typical FM broadcast band is 88-108 MHz, while a typical AM broadcast band is 540-1660 KHz, making the FM signal wavelength 100 times shorter.
Why does the hystresis loop of the schmitt trigger circuit changes when you change the frequency from 100 hz to 10khz?
because your frequency has changed. The distance between waves is shorter at 1000hz than at 100hz.
Can a high frequency carrier wave travel longer distance than low frequency carrier wave?

What is the average cost to run a typical nuclear power plant?
It'l be in the range of £100-£200 million a month
