What is the speed of a wave that has a wavelength of 10 m and a frequency of 34 hz?
340 m/s
What is the energy J of photon with a wavelength of 601nm?
for a photon energy= Planks Constant * frequency and frequency= speed of light/wavelength so E= hc/(wavelength) h= 6.63E-34 J/s c= 3E8 m/s Plug n' Chug
What is frequency of ultraviolet light with wavelength 2.94x10-8m?
You need to use the equation c= wavelength * frequency , where c is the speed of light (2.99792458 * 108 m/s) Solve the equation for frequency, frequency=c/wavelength frequency = 1.02 * 1016 s-1 or the unit could be Hz which equals 1 s-1
Which form of electromagnetic radiation has highest level of energy how can you tell?
Energy (E) of photons of electromagnetic radiation is given by Planck's equation ..E = hf .. h = Planck constant (6.625^-34 Js), f = frequency (Hz)So E is proportional to frequency .. radiation with the highest frequency is Gamma
How do you find wavelength if you've been given the energy?
The easiest way would be to find a descriptive article on the internet that shows the visible colors spread out with some wavelengths labeled. There, you can find the approximate wavelengths for light of various colors. If you don't know the color of the light, then in order to find its wavelength, you'd need to know either its frequency or the energy of a photon (quantum). Energy of a photon = h f h = Planck's Konstant = about 6.63 x 10-34 joule-second f = frequency of the light wave or photon But the frequency is (speed of light)/(wavelength) so, Energy = h c/wavelength . If you know either the energy of the photon or its frequency, you can use this stuff to find its wavelength. In this discussion, I've toggled back and forth a few times between the frequency/wavelength of the quantum and the frequency/wavelength of the light wave. Don't worry. They're the same.
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.
What is the speed of a wave that has a wavelength of 10 m and a frequency of 34 hz?
340 m/s
What is the frequency in hertz and the energy in joules of an x-ray photon with a wavelength of 2.32 Å?
For the frequency, first convert the wavelength to meters (divide the number of Angstroms by 1010), then use the formula: wavelength x frequency = speed. Using the speed of light in this case. Solving for frequency: frequency = speed / wavelength. To get the photon's energy, multiply the frequency times Planck's constant, which is 6.63 x 10-34 (joules times seconds).
What is the energy J of photon with a wavelength of 601nm?
for a photon energy= Planks Constant * frequency and frequency= speed of light/wavelength so E= hc/(wavelength) h= 6.63E-34 J/s c= 3E8 m/s Plug n' Chug
What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73 X 10 to the 20 HZ?
Wavelength = (speed) / (frequency)= (3 x 108) / (4.32 x 1020) = 6.94 x 10-13 meter = 6.94 x 10-4 nanometers
What is frequency of ultraviolet light with wavelength 2.94x10-8m?
You need to use the equation c= wavelength * frequency , where c is the speed of light (2.99792458 * 108 m/s) Solve the equation for frequency, frequency=c/wavelength frequency = 1.02 * 1016 s-1 or the unit could be Hz which equals 1 s-1
A microwave photon has a wavelength of 21 cm What is its energy?
We have an equation for that: lambda = c / (f * sqrt(epsilon)) where lambda = wavelength in [m] c = the speed of light in vacuum = 3E+8 [m/s] epsilon = the dielectric constant of the medium in question = 1 for air or vacuum Hence, the photon frequency in air or vacuum = c / lambda = 3x108 / 0.21 [s-1] = 1.43 [GHz]. The photon energy, E = h * f, where h = Planck's constant = 6.63x10-34 [Js]. E = 6.63x10-34 [Js] * 1.43 [GHz] = 9.5x10-34 [J]
What is the relationship between wavelengths and energy?
The amount of energy is inversely related to the wavelength of the radiation: the shorter the wavelength, the greater the energy of each photon.This was originally discovered by Max Planck who identified a co-effiecient of proportionality that related a photon's energy to its frequency. This co-effiecient is known as the Planck constant and allows the energy of a photon to be found using the following relation (known as the Planck relation or the Planck-Einstein equation):E = hv (Eq. 1)Where:E = Energy (J)h = Planck constant (6.62606896×10−34 Js)v = frequency (Hz).For electromagnetic radiation travelling through a vacuum:v = c / λ(Eq. 2)Where:c = speed of light in a vacuumλ = wavelength (m)As such this can be substituted into the Planck relation to give the following: E = hc / λ(Eq. 3)From equations 1 and 3 it can be seen that a photon's energy is directly proportional to it's frequency and inversely proportional to its wavelength.

What are the equations for wavelength and frequency of light?
The speed of light is fixed and so the wavelength and the frequency of light are related like this:wavelength * frequency = speed of lightYou just have to be careful your units match up. Often wavelengths of light are listed in nanometers, or nm, while the speed of light is often given in meters per second, or m/s. Make sure everything is in terms of meters or your answer will be way off. Frequency is almost always given in terms of 1/seconds, which is also called a Hertz. See the Web Links for more information about the electromagnetic spectrum.
What is the energy of a photon of a red light having a frequency 4.48 x 10 14Hz?
Since the wavelength times the frequency is equal to the speed of the wave, all you need to do in this case is divide the speed of light (in meters/second) by the frequency. The answer will be in meters.
How can you determine the frequency of a light wave?
to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.
