Which material transmits the most sound energy?
air is a good transmitter of sound energy. also metals are very good due to there metallic bonding properties. most materials are best at transmitting different frequencies, aka their resonant frequency.
How is the relationship between the frequency and the wavelength of electromagnetic energy?
Frequency is inversely proportional to wavelength (higher frequency means a shorter wavelength). Frequency is directly proportional to the energy of the wave (higher frequencies correspond to higher energies).
How does the wavelength of a wave change when the frequency changes?
Usually with electromagnetic waves, the frequency and energy is opposite to the wavelength. An EM wave such as radiowaves have huge wavelengths, slow frequencies and small amounts of energy. An EM wave such as X-rays have tiny wavelengths, fast frequencies and large amounts of energy.
If two waves traveling at the same speed have different frequencies which wave has more energy?
Which ever is the highest frequency
Does the frequency is inversely proportional to wavelength?
Yes. The wavelength times the frequency is equal to the speed of the wave - and the speed is usually almost the same for different frequencies.

Why the strength of the carrier in FM spectrum is not constant?
You can think of it this way: When the FM carrier is modulated, you know that "sidebands" appear in the frequency spectrum, at frequencies both above and below the carrier frequency. These are new signals, with energy being transmitted at each sideband frequency. But the power out of the transmitting hardware hasn't changed. Unlike the case with AM, the modulation process most likely takes place in a low-level stage of the transmitter, and the modulator supplies no RF power. Since new signal energy appears at new frequencies separated from the carrier frequency, the energy has to come from somewhere. No RF energy is added in the transmitter, so the sideband energy comes out of the carrier signal. That's a very unscientific and un-mathematical way to look at it, but I don't think it's essentially inaccurate.
What is a lump circuit?
A lump circuit is a circuit that concentrates energy in specific frequencies. This is done instead of distributing it over a length of time.
What do light waves of greater frequency have?
The meaning of a high frequency wave is a shorter wavelength.For electromagnetic waves in general (including light):* At greater frequencies, you get shorter wavelengths.* At greater frequencies, you get more energy per photon.
How is the relationship between the frequency and the wavelength of electromagnetic energy?
Frequency is inversely proportional to wavelength (higher frequency means a shorter wavelength). Frequency is directly proportional to the energy of the wave (higher frequencies correspond to higher energies).
What is light frequencies?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.

How wireless power outlet works?
High frequency transmitter sends energy towards a receiving magnetic coil that picks the energy up.
What is the frequency of a hydrogen atom?
An atom doesn't have a frequency. It can vibrate with many different frequencies. It can absorb radiation of different frequencies under different circumstances. For instance, electrons moving between various energy levels absorb and release characteristic frequencies of visible and ultra-violet light, and in a magnetic field radio frequency energy can be absorbed as the nucleus moves from one spin state to another. Bonds between hydrogen and other atoms absorb energies in the infra red. All these things give spectra of various frequencies, not an individual frequency.
If two waves traveling at the same speed have different frequencies which wave has more energy?
Which ever is the highest frequency
What is the working principle of transmitter?
There are many types of transmitters. Thesimplest is the Amplitude Modulated (AM) transmitter. This is an oscillator that cycles at a predetermined frequency. This oscillator puts out a level of energy that is varied by the sounds that you desire to transmit. This variance is done from 100% of the signal to 0%. The output then is two frequencies combined one at the stations frequency and one at the frequency of the sound transmitted. The receiver throws away the transmission frequency and amplifies the frequency of the sound.Bottom line is you only hear the sound stuck into the transmitter.F.M. is the same as AM but instead of varying power, we vary the frequency with the desire sounds we want to hear. The receiver sees that variance and converts that to sound.Phase shift, DSB, SSB and the others are merely more complex variances to these basics.
