When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle.

Light is Quantized The photons of different colors or different types of light have different frequencies and therefore have different energies. At a particular frequency, one photon is the smallest amount of light that can exist.

1s electron being close to the nucleus experiences more force of attraction than2s– electron which is away from the nucleus. The questions posted on the site are solely user generated, Doubtnut has no ownership or control over the nature and content of those questions.

Electron filling the in the atom is done from lower energy orbital to higher energy orbital. Therefore 1s has lower energy compared to 2s. …

Frequency is not quantized, and has a continuous spectrum. As such, a photon can have any energy, as E=ℏω. for V≠0, the energy spectrum is discrete.

quantization rule, which states that the action integral of the system must equal a half-integer times Planck’s constant. This is an asymptotic approximation valid only for small values of Planck’s constant. Only the simplest system with a Hamiltonian of the form Hip, q) = (p2/2m)+ V(q) has been considered.

Sitting on a Flight of Stairs It should be obvious to the students that they cannot sit at any arbitrary height on a flight of stairs, they must choose a step to sit on. If the height of a step is h, the allowed positions are n h, which are quantized.

We simplify time into discrete numbers. Another example is capturing a digital image by representing each pixel by a certain number of bits, thereby reducing the continuous color spectrum of real life to discrete colors. Quantization, in essence, lessens the number of bits needed to represent information.

The maximum error possible is equivalent to a voltage corresponding to ±(½) of an LSB. For an ideal digital recorder, this quantization would be the only source of error in the recorded samples. For a real digital recorder, this error sets the absolute upper limit on the accuracy of the readings.

Quantization, involved in image processing, is a lossy compression technique achieved by compressing a range of values to a single quantum value. When the number of discrete symbols in a given stream is reduced, the stream becomes more compressible.

In signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal. A common example is the conversion of a sound wave (a continuous signal) to a sequence of samples (a discrete-time signal). A sample is a value or set of values at a point in time and/or space.
