Consider photons emitted from an ultraviolet lamp and a TV transmitter. Which is the greater wavelength Which is the greater momentum?
AlicePapa
Good luck,
Greater wavelength=TV. frequency= the number of wave cycles(peak, trough, peak) per time unit. The higher the frequency, the more times the wave cycles, and the shorter the wavelength.
Greater Energy=Ultraviolet lamp. By Placks constant, E(energy) =h(planck's constant which is the energy of a photon divided by it's frequency) / f(the frequency of that photon). Planck's constant is almost irrelevant, so the greater the frequency, the greater the energy.
Greater frequency=Ultraviolet lamp. Planck's constant and light spectrum.
Greater Momentum= Ultraviolet lamp. Electron diffraction, Wavelength=h(planck's constant) / momentum. rearrange it as M=h/W. The greater the wavelength, the smaller the momentum, and visa versa.

How do you find wavelength of an alpha particle when given the velocity?
use de Broglie's wavelength: lambda = h/mv
What is the characteristic wavelength of the electron when an electron is accelerated through a particular potential field if it attains a speed of 9.38x10 to the power of 6 ms?
A characteristic wavelength of an electron can be known as the DeBroglie Wavelength. It is a formula in physics which relays energy and momentum.
Why is de broglie wavelength associated with macroscopic objects is not observed in daily life?
Because such a wavelength is way too small to be significant. The de Broglie wavelength is inversely proportional to an object's momentum (mass x speed).
If you know the wavelength of an electromagnetic wave in a vacuum you can calculate its?
Momentum, energy, frequency, and wave number (but not wave vector.)
When particles are in motion they have?
Particles in motion will generally have kinetic energy, or momentum. Cumulative effects of motions of groups of particles (Brownian motion) is perceived as heat. According to the duality of matter (wave-particle), a moving particle can also be said to have a wavelength (De Broglie wavelength) associated with its mass and momentum.
What is the momentum of an x-ray beam that has a wavelength of 5.0E-9m?
The momentum of an X-ray beam does not change based on a wavelength of 5.0E-9m. The momentum of an x-ray beam is the same as the speed or momentum of light.
a proton and electron have the same kinetic energywhich has longer wavelength?
the electron would have the longer wavelength b/c the proton has more momentum and λ=h/p (λ is wavelength, h is planc's constant and p is momentum)

What is the de Broglie wave FORMULA?
Wavelength equals Planck's Constant divided by momentum.
What is physical significance of momentum?
Physically, linear momentum is "stored force" as that momentum is dissipated. Consider the linear momentum of a train carrying coal coming to a stop, quickly.
How to calculate the wavelength?
This question is from Bohr's atomic model. The total length of the orbit is an integral multiple of the wavelength of an electron. The relation given by 2(pi)(radius)=n(wavelength), where n is the principal quantum number. Proof of this came later from De-Broglie's hypothesis, (wavelength)=h/(linear momentum) It is- (wavelength)=h/mv .....I From Bohr's model (Quantization of angular momentum), mvr=nh/2(pi) So, 2(pi)r=n(h/mv) From I, 2(pi)r=n(wavelength)

Can abody have energy without having momentum?
yes. a body can have energy without momentum also. consider a body at a height 'h' m above the ground level , potential energy contained is = mgh but , as the velocity is 0 we can consider that the momentum of the body is 0

Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
