are wavelengths and frequencies quantized?
160601
One of the most important characteristics of these spectra is that they are discrete. By this we mean that only certain wavelengths, and hence frequencies, are emitted. ... If frequency and energy are associated as ΔE = hf, the energies of the electrons in the emitting atoms and molecules are quantized.

Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430–750 terahertz (THz).

Both are electromagnetic waves, quantized as photons. The only difference is the frequency of oscillation. Only wavelengths between 390 and 700 nm (approximately) are visible to humans. Radio waves are much longer (have much lower frequency).

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength.

The frequency of a photon is calculated by the formula: λ = c ν \lambda=\tfrac{c}{\nu} λ=νc , where с = 3 ∗ 1 0 8 с=3*10^8 с=3∗108 m/s. A wavelength in nm translate to m: 159 nm = 1.59 ∗ 1 0 − 7 1.59*10^{-7} 1.

Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave's wavelength is generally associated with color, and its amplitude is associated with brightness.

Frequency is generally measured in Hertz, which are units of cycles per second. Color is the frequency of visible light, and it ranges from 430 trillion Hertz (which is red) to 750 trillion Hertz (which is violet). ... When it comes to light waves, violet is the highest energy color and red is the lowest energy color.

The energy E, frequency f, and wavelength λ of a Photon are related as follows: E=hf=hc/λ, where c is the speed of light and h is Planck's constant. So, given any one, the other two can be easily calculated. (This is assuming the photon is propagating in a vacuum.

Measuring electromagnetic radiation Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts. Each of these three quantities for describing EM radiation are related to each other in a precise mathematical way.

In the electromagnetic spectrum there are many different types of waves with varying frequencies and wavelengths. They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light.

Wavelength is commonly designated by the Greek letter lambda (λ). ... Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

To calculate the wavelength, you need to know either the frequency or the energy of the radiation. 590 kHz? E=hcλ or λ=hcE , where h is Planck's constant.

The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz. There is a wide range of subcategories contained within radio including AM and FM radio.

Frequency is generally measured in Hertz, which are units of cycles per second. Color is the frequency of visible light, and it ranges from 430 trillion Hertz (which is red) to 750 trillion Hertz (which is violet). Waves can also go beyond and below those frequencies, but they're not visible to the human eye.

Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

Wavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases. The inverse proportionality is illustrated in Figure 2. This figure also shows the electromagnetic spectrum, the range of all types of electromagnetic radiation.
