There are two kinds of waves. One is mechanical for which the energy is given by the expression 2 m pi2 a2 nu2 . a is the amplitude of vibration and nu is the frequency of vibration. Hence in case of mechanical waves, energy is proportional to the square of the amplitude.
But in case of electromagnetic wave photon concept is introduced as quantum of energy. The energy of thee quantum is given by the expression h nu. Here h is Planck's constant and nu the frequency of radiation. Hence the energy content of each photon is proportional to the frequency of radiation.
But the intensity of radiation is computed by the number of photons per second.
The energy of a wave is directly proportional to its frequency and inversely proportional to its wavelength. This means that waves with higher frequencies have higher energy, while waves with shorter wavelengths also have higher energy. The relationship is described by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency.

What do you need to figure out wave speed?
To determine wave speed, you need to know the wavelength of the wave and the frequency of the wave. The formula for calculating wave speed is: speed = frequency × wavelength.
What is the energy of an electromagnetic wave that has a wavelength of 9.0 10-6 m?
The energy of an electromagnetic wave is proportional to its frequency. You can calculate the frequency using the formula: frequency = speed of light / wavelength. Once you have the frequency, you can determine the energy using the formula: energy = Planck's constant * frequency.
What do frequency and wavelength have in common?
Frequency and wavelength are both properties of waves. They are inversely related, meaning that as frequency increases, wavelength decreases, and vice versa. Together, they determine the energy and behavior of a wave.
What happens to the frequency and energy carried by an electromagnetic wave as the wavelength decreases?
As the wavelength of an electromagnetic wave decreases, the frequency of the wave increases. This means that the energy carried by the wave also increases, as energy is directly proportional to frequency. Therefore, shorter wavelength corresponds to higher frequency and energy in an electromagnetic wave.
What can be determine from the frequency and wavelength of a wave?
The velocity of the wave

How are wavelength frequency and energy are related?
Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength

As the wavelength of an electromagnetic wave decreases, the frequency of the wave increases. This means that the energy carried by the wave also increases, as energy is directly proportional to frequency. Therefore, shorter wavelength corresponds to higher frequency and energy in an electromagnetic wave.

The velocity of the wave
How do you figure out the speed of a wave?
To determine the speed of a wave, you need to know the frequency of the wave and its wavelength. You can calculate the speed of the wave by multiplying the wavelength by the frequency. The formula for the speed of a wave is speed = frequency x wavelength.
If wavelength increases what happens to frequency and wave energy?
If wavelength increases, frequency decreases inversely. Wave energy remains the same since it is determined by amplitude and not by wavelength or frequency.
How do you double the wavelength of a wave?
To double the wavelength of a wave, you need to decrease its frequency by half. Wavelength and frequency are inversely proportional - as wavelength increases, frequency decreases, so doubling the wavelength requires halving the frequency. This change in wavelength can affect the characteristics of the wave, such as its speed and energy.
How is wave speed determine?
by dividing wavelength by frequency
What happens to the wavelength of a wave when the energy is increased?
If you are talking about an electromagnetic wave; energy is proportional to frequency (E=hf), and frequency is inversely proportional to wavelength (wavelength equals velocity divided by frequency). So when the wavelength is increased, the energy is decreased.
How does the energy assoicated with waves change wave length changes?
As the wavelength of a wave decreases, the energy associated with the wave increases. This is because the energy of a wave is directly proportional to its frequency, and since frequency is inversely proportional to wavelength (wavelength = speed of wave / frequency), a decrease in wavelength results in an increase in frequency and energy.
