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.
What is the frequency and time period and wave length of waves if 10 waves pass every 20 seconds?
To get the frequency, divide the number of waves (10) by the time it takes for those waves to pass (20). The answer is in hertz.The period is the reciprocal of the frequency. There is not enough information to determine the wavelength.
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 wavelength that has a frequency of 100 Hz?
3000000m
Does higher frequency mean higher pitch?
The only way to compare these "energies" is if they are altered from the same source. Otherewise it's apples and oranges. Take a 5 watt radio signal. Wether it's AM or FM, it's still a 5 watt signal.
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?

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).
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.
What is the average cost to run a typical nuclear power plant?
It'l be in the range of £100-£200 million a month
What does frequency mean in science term?
Frequency, referring to sound, is the amount of complete waves every second that produce sound. For example: High pitched sounds, like the sound that whistles make, have a high frequency (lots of waves per second). And Low pitched sounds like the sound that a subwoofer makes have a low frequency (Not so many waves per second) The average human can hear from 20hz (cycles per second) up to around 20,000hz (cycles per second)

What is the longest wavelength?
There is no longest wavelength. In the electromagnetic spectrum extremely low frequency waves can have wavelengths of less than 100 megametres (100,000 kilometres or 10^8 metres). Gravitational waves are likely to have much longer wavelengths.
How much is 100 million in crores?
100 million = 10 crores.100 million = 10 crores.100 million = 10 crores.100 million = 10 crores.

To get the frequency, divide the number of waves (10) by the time it takes for those waves to pass (20). The answer is in hertz.The period is the reciprocal of the frequency. There is not enough information to determine the wavelength.
