Line Spectrum
They have fixed energy values.
Each energy level corresponds to an exact amount of energy needed by the electron to orbit the nucleus. Transitions from a higher energy level to a lower energy level correspond to the difference in the energy needed for an electron to occupy those two energy levels. This difference creates the emission spectrum.
Atoms give line spectra because they have discrete energy levels due to quantized electron orbits. When electrons transition between these levels, they emit or absorb photons of specific wavelengths, resulting in distinct lines in the spectrum. Molecules, on the other hand, have more complex energy levels due to rotational and vibrational motion, leading to a wider range of possible energy transitions and thus a band spectrum.

Continuous change refers to a smooth, gradual change that occurs over a range of values without specific breaks or steps in between. Quantized change, on the other hand, involves discrete, distinct steps or levels where the values can only change in specific increments or units. An example of continuous change could be temperature increasing gradually over time, while an example of quantized change could be the energy levels of electrons in an atom jumping between specific values.

I believe it can - the energy of a photon is the product of the frequency and Plank's constant - and as far as I know, the frequency is not quantized.

The light spectrum can be viewed as a slinky. When compressed, the light waves change to the blue end of the spectrum. When stretched, the the light changes to the red end of the spectrum. Physicists know that our universe is expanding because galaxies further away change to the red end of the spectrum. This means the galaxies were once closer together in the past than what they are now. This is one of the many pieces of evidence that supports the Big Bang Theory.

the line spectrum of the hydrogen spectrum indicates that only certain energies are allowed for the electron of the hydrogen atom. In other words, the energy of the electron in the hydrogen atom is quantized.

They have fixed energy values.
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
