Explanation

A Bloch wave represents the motion of an electron in a periodic potential. 

Bloch's theorem describes the wavefunction of electrons in a periodic potential, meaning the potential repeats itself regularly throughout the crystal lattice.

The wavefunction of a Bloch electron is then a product of a plane wave and a periodic function with the same periodicity as the potential. 

Explanation

Explanation

The distance between two successive particles that are in the same state of vibration is called Wavelength.

It is measured as the distance between two consecutive crests or troughs in a wave.

Explanation

The value of Planck's constant is 6.63 × 10⁻³⁴ Js.

This constant is fundamental in quantum mechanics.

It relating the energy of a photon to its frequency.

Explanation

The electric intensity between two oppositely charged plates in the middle region is uniform.

This is because the electric field strength remains constant between the plates.

It assuming they are large and parallel, and the charges are evenly distributed.

Explanation

If the armature current is maintained at 200% of its rated value, the machine's rated current would be 2 times the rated current.

This is because the current is doubled from its rated value.

Explanation

The transportation delay in a distribution system causes reduced stability because it produces phase lag.

This phase lag affects the system's response and stability, leading to potential instability and oscillations.

Explanation

The transducer which converts physical quantities to pulses is called a Digital Transducer.

It outputs a digital signal or pulse train that corresponds to the measured physical quantity.

Explanation

In the left-hand rule, the thumb represents the direction of the force on the conductor.

This rule is used to determine the force experienced by a current-carrying conductor within a magnetic field.

Explanation

When a star is moving away from an observer, the wavelength of the light it emits appears to be stretched or shifted toward the red end of the spectrum. This phenomenon is known as redshift.
