The de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
Hence,the de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.
