Explanation

The potential through which an electron should be accelerated to lift an atom's electron from the ground state to a higher state is known as excitation potential.

This energy excites the electron without completely removing it from the atom.

Explanation

The Lyman series falls in the ultraviolet region.

It corresponds to electronic transitions in a hydrogen atom where the electron drops to the n=1 energy level, emitting ultraviolet radiation.

Explanation

Photoelectric effect does not demonstrate the wave nature of light; it shows light behaving as particles (photons).

The phenomena of diffraction, polarization, and interference are clear evidence of light's wave nature.

Explanation

The de-Broglie wavelength (λ) is given by the formula:

λ = h / (m × v)

Where:

h = Planck's constant = 6.626 × 10^-34 J s

m = mass of the particle = 10^-30 kg

v = velocity of the particle = 10^6 m/s

Substituting the values, we get:

λ = (6.626 × 10^-34 J s) / (10^-30 kg × 10^6 m/s)

= (6.626 × 10^-34 J s) / (10^-24 kg m/s)

= 6.626 × 10^-10 m

So, the de-Broglie wavelength associated with the particle is 6.6×10^-10m.

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

A diode characteristic curve is a plot between voltage and current.

It shows the relationship between the applied voltage across the diode and the resulting current.

It indicating the diode's behavior in both forward and reverse bias.

Explanation

Full wave rectification is given by four diodes connected in bridge type arrangement.

This configuration allows both halves of the A.C. waveform to be used, producing a smoother and more efficient output compared to half-wave rectification.

Explanation

The component of electronics that acts as a rectifier is a diode.

Diodes allow current to flow in one direction only.

It enabling the conversion of alternating current (A.C.) into direct current (D.C.) by blocking the reverse flow.

Explanation

In an ideal transformer, power input is equal to power output.

This is based on the principle of conservation of energy.

It means that the transformer is assumed to have no losses; therefore, the input power (from the primary coil) equals the output power (to the secondary coil).

Explanation

The incorrect statement is "Distance between consecutive nodes is 1 wavelength."

The distance between consecutive nodes is actually 1/2 wavelength, as nodes are points of no displacement in standing waves.

It occurring at intervals of half the wavelength along the string.
