What affects velocity of electron in the photoelectric effect?
The velocity of an electron in the photoelectric effect is primarily determined by the energy of the incident photon. If the photon energy is greater than the work function of the material, the electron can be ejected with higher velocity. Additionally, factors like the electric field in the material can influence the electron's velocity.
Is the momentum of an electron constant?
No, the momentum of an electron can change depending on its velocity and direction of motion. Momentum is a vector quantity that is the product of an object's mass and velocity. So if the velocity of an electron changes, its momentum will also change.
Determine wavelength for electron having velocity 15.0 the speed of light?
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 information do you need to determine velocity?
You need to have displacement and time for you to determine the velocity.
What is the velocity experienced by an electron in an electric field?
The velocity experienced by an electron in an electric field depends on the strength of the field and the mass of the electron. The velocity will increase as the electric field strength increases. The electron will accelerate in the direction of the electric field.
Which are two factors determine an objects velocity?
the two factors that determine an object's velocity is SPEED and DIRECTION.By: Arjane Lee Lagasca
What is the direction of the magnetic force on the electron?
The direction of the magnetic force on an electron is perpendicular to both the electron's velocity and the magnetic field it is in.
How can one determine velocity using momentum?
To determine velocity using momentum, you can use the formula: momentum mass x velocity. Rearrange the formula to solve for velocity: velocity momentum / mass. By dividing the momentum by the mass of the object, you can calculate its velocity.
What is the electron velocity formula used to calculate the speed of electrons in a given system?
The formula used to calculate the speed of electrons in a given system is v e/m, where v represents the velocity of the electron, e is the charge of the electron, and m is the mass of the electron.
How can one determine the relative velocity between two objects?
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
How can one determine velocity from momentum?
To determine velocity from momentum, you can use the formula: momentum mass x velocity. By rearranging the formula, you can solve for velocity by dividing momentum by mass. This will give you the velocity of an object based on its momentum and mass.
How can one determine velocity by using acceleration and time?
To determine velocity using acceleration and time, you can use the formula: velocity initial velocity (acceleration x time). This formula takes into account the initial velocity, acceleration, and time to calculate the final velocity.
