Zorluk: OrtaWaves, Sound, and Light

The visible light spectrum consists of electromagnetic radiation spanning various wavelengths and frequencies. Arrange the following colors of visible light in order of increasing frequency, from lowest frequency to highest frequency.

  1. 1Red light
  2. 2Yellow light
  3. 3Blue light
  4. 4Violet light

Cevap

The correct order from lowest frequency to highest frequency is Red light, Yellow light, Blue light, and Violet light.
Electromagnetic waves in the visible spectrum have frequencies that are inversely related to their wavelengths. Red light has the longest wavelength (around 700 nm700\text{ nm}) and thus the lowest frequency. As wavelength decreases across the spectrum toward violet (around 400 nm400\text{ nm}), wave frequency increases progressively from yellow to blue to violet.

Adım Adım Çözüm

1
Recall the fundamental wave relationship connecting wave speed, frequency, and wavelength.
Since all electromagnetic waves travel at the same speed in a vacuum (c=fλc = f\lambda), frequency is inversely proportional to wavelength (f=c/λf = c / \lambda).
This relationship demonstrates that colors with the longest wavelengths have the lowest frequencies, while colors with the shortest wavelengths have the highest frequencies.
2
Determine the relative wavelengths and frequencies of the given visible light colors using the standard spectral sequence.
From longest to shortest wavelength, the visible spectrum follows the sequence: Red →\rightarrow Orange →\rightarrow Yellow →\rightarrow Green →\rightarrow Blue →\rightarrow Indigo →\rightarrow Violet.
Mapping the colors to this sequence directly determines their relative positions regarding frequency.
3
Arrange the specified colors in order of increasing frequency.
The sequence from lowest frequency (longest wavelength) to highest frequency (shortest wavelength) is Red light →\rightarrow Yellow light →\rightarrow Blue light →\rightarrow Violet light.
This orders the items accurately according to the specified physical criteria.
