Q. When an electron is accelerated through a potential difference V?
An electron accelerated through a potential difference V passes through a uniform transverse magnetic field and experiences a force F. If the accelerating potential is increased to 2V, the electron in the same magnetic field will experience a force.
Q. What is the relation between de Broglie wavelength and voltage?
Note: The input only allows an acceleration voltage up to Va=100000V….Calculation of the de Broglie wavelength.

| Accelerating voltage E[kV] | Relativistically corrected accelerating voltage E*[kV] | Wavelength of electron λ[pm] |
|---|---|---|
| 1 | 1.0010 | 38.764 |

Q. What is the de Broglie wavelength of an electron accelerated by a voltage of 50 V?
0.173 nm
Q. Is kinetic energy of free electron is doubled its de Broglie wavelength will change by factor?
If the kinetic energy of a free electron doubles, its de Broglie wavelength changes by the factor. times. Correct answer is 1. This is the correct option.
Q. What is the value of de Broglie wavelength of an electron when it is accelerated?
1.23V
Q. When an electron is accelerated by potential difference V 5000 volts then the de Broglie wavelength becomes?
Thus de-Broglie wavelength of the electron will become half if the accelerating potential is increased by a factor of 4.
Q. What has the smallest de Broglie wavelength?
α-particle
Q. Which of the following has longest de Broglie wavelength?
β-particle
Q. Which of the following has maximum de Broglie wavelength moving with same speed?
Electron has the least mass, so its wavelength is maximum.
Q. Which of the following has maximum wavelength of matter wave?
Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Q. Which of the following has the largest de Broglie wavelength all have equal velocity )?
Electron
Q. Which Colour has the largest wavelength?
red light
Q. Which particle has longest wavelength?
β particle
Q. What is the wavelength of matter wave?
Particles of matter also have a wavelength, called the de Broglie wavelength, given by λ=hp λ = h p , where p is momentum. Matter is found to have the same interference characteristics as any other wave.
Q. How is wavelength defined?
Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave. Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency.
