Speed of electron as compared to speed of light is: n = 15% c = 299792458 [m/s]
v = c*n/100 = 4.5 *10^7 [m/s]
So corresponding wavelength as given by the de Broglie equation: h - Planck's constant, m0 - the mass of the electron at zero velocity;
lambda = h/p = h/(v*m0) = 6.62606876*10^-34/(4.5 *10^7*9.10938188*10^-31) = 1.61642*10^-11 [m] = 0.16 [angstroms]

What is the frequency of light having a wavelength of 447 nm?
Wavelength = Velocity / FrequencyTherefore:Frequency = Velocity / WavelengthVelocity = c, the speed of light, which is 299,792,458m/s.We know the wavelength is 413nm, which is 4.13*10-7m, so our equation is:f = (3.00 * 108) / (4.13 * 10-7) = 7.259 * 1014Hz
When did Louis de broglie discover electron waves?
Wavelength is inversely proportional to momentum (of a particle such as an electron - or any having mass) was proposed by LDB for his doctoral thesis in 1924
If an electron vibrates up and down 1000 times each second it generates an electromagnetic wave having a?
Frequency of 1000 Hz. (Wavelength of 300 kilometers.)
Does the color of light affect the brightness of light?
The simplest answer to the question is to refer to the propagation conditions in a vacuum, where the direction in which the light is traveling doesn't matter and there are are no other effects to confuse the picture ... just the light and the empty space with its intrinsic electrical properties. There, neither the color of the light, nor its wavelength, frequency, or intensity, makes any difference in its speed. A flash of red, a flash of violet, a pulse of radio waves, and a zap of X-rays -- all emitted at the same time from the same star a million billion miles away from us -- will all arrive on Earth together 170 years later, having traveled together all at the same speed.
What is a light having one wavelength called?
At a single wavelength, it is called monochromatic
What is the frequency of light having a wavelength of 447 nm?
Wavelength = Velocity / FrequencyTherefore:Frequency = Velocity / WavelengthVelocity = c, the speed of light, which is 299,792,458m/s.We know the wavelength is 413nm, which is 4.13*10-7m, so our equation is:f = (3.00 * 108) / (4.13 * 10-7) = 7.259 * 1014Hz
Calculate the velocity of a wave having frequency of 0.5 Hz and wavelength of 5 m?
The speed of a wave = (frequency) x (wavelength) = 2.5 meters per second.

How would one determine the tensor between a sinusoidal wavelength and 4-dimensional ellipsoidal manifold?
I think you can determine this tensor by not making it up and having it be possible.
Calculate the frequency of a wave having a velocity of 15 m s and wavelength of 3 m?
(frequency) = (speed) / (wavelength) = (15 m per sec) / (3 m) = 5 per sec = 5 Hz.
If an electron vibrates up and down 1000 times each second it generates an electromagnetic wave having a?
Frequency of 1000 Hz. (Wavelength of 300 kilometers.)
Why is it impossible to know precisely the velocity and position of an electron at the same time.?
This is because of the Heisenberg uncertainty principle. It is a part of quantum mechanics. It has to do with an electron having properties of both a particle and and wave. If you only imagine an electron to be a particle, this can be somewhat explained by the process of measuring the position or velocity of the electron. If the data is measured with light, then when a photon hits the electron, it changes the electrons speed and position. We may be able to find one, but in the process, the other will be changed.
Did scrodinger discover the neutrons?
He developed an equation from which one can derive the probability of an electron having a specific value for location or velocity. He had nothing whatsoever to do with the discovery of neutrons.
The path that an electron travels around a nucleus is called an?
The "orbit" of an electron is the energy level that electron happens to be in. When we get to particles the size of electrons, the concept of electrons following a specific path begins to fall apart. We can no longer talk about an electron being somewhere and having a specific velocity; we can only talk about the PROBABILITY of an electron being at a specific place, as well as the most likely velocity at a given orbit.
How are x-rays and earthquake waves similar?
They are both transverse waves, albeit having different wavelength and frequency. I think that velocity of the waves will also be different as x-rays travel at the speed of light.
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
