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.

What determine the color of a light wave?
Its wavelength (or frequency).
How much energy does a wavelength have if it has a wave of 3.01x10-9m?
A wavelength doesn't have energy. The wave does. The details depend on the type of wave. Assuming an electromagnetic wave, you have to multiply the frequency by Plank's constant. To find the frequency, divide the speed of the wave by the wavelength.
What does the wavelength of an EM wave tell about its energy?
The shorter the wavelength of a wave, the higher its energy.
What is the relationship of wavelength and energy in a wave?
Depends on the wave. In electromagnetic waves, a shorter wavelength means a higher frequency - and the energy of a photon is directly proportional to frequency.
As the wavelength of a wave increases on the electromagnetic spectrum what happens to the energy of the wave?
As a wavelength increases in size, its frequency and energy (E) decrease.
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
What determine the color of a light wave?
Its wavelength (or 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 is wave speed determine?
by dividing wavelength by frequency

What decreases as the frequency of a sound wave increases?
Wavelength.
What is the relationship of wavelength and energy in a wave?
Depends on the wave. In electromagnetic waves, a shorter wavelength means a higher frequency - and the energy of a photon is directly proportional to frequency.
As the wavelength of a wave increases on the electromagnetic spectrum what happens to the energy of the wave?
As a wavelength increases in size, its frequency and energy (E) decrease.
What can be determine from the frequency and wavelength of a wave?
The velocity of the wave
Determine the energy and wavelength of a wave with a frequency of 3.6X 1016 hertz Would this be a wave of interest to nuclear medicine?
assuming the wave is electromagnetic... the energy of a single photon of that frequency is given by the formula E=hf where E= energy of the photon h=the Planck constant f= the frequency of the photon From this the energy of the photon is the Planck constant (6.63 x10-34) multiplied by the frequency 3.6x1016 Hz. E= 23.9x10-18 Joules. The wavelength of any wave is determined by the equation wave speed = frequency x wavelength. thus, the wavelength is the wave speed divided by the frequency. since all electromagnetic waves travel at the speed of light then... wavelength = 3x108 / 3.6x1016 wavelength = 0.83x10-8 = 8.3x10-9 metres. The electromagnetic radiation corresponding to this energy and wavelength is ultraviolet radiation and may be of interest to nuclear medicine.
The types of radiant energy differ in their?
Frequency or wave length.
