Zorluk: KolayWaves, Sound, and Light

When white light passes through a prism, it disperses into different colors of the visible spectrum. What is the correct order of the following colors of visible light when arranged from lowest wave frequency to highest wave frequency?

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

Cevap

The correct sequence from lowest frequency to highest frequency is Red light, Yellow light, Green light, Violet light.
In the visible light spectrum, colors progress in order of decreasing wavelength and increasing frequency according to the sequence Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV). Red light has the longest wavelength and lowest frequency, followed by yellow light, green light, and finally violet light, which has the shortest wavelength and highest frequency.

Adım Adım Çözüm

1
Recall the order of the visible light spectrum from longest wavelength to shortest wavelength.
The standard sequence of visible light colors is Red, Orange, Yellow, Green, Blue, Indigo, and Violet (ROYGBIV).
Visible light wavelengths decrease progressively from red light (~700 nm) to violet light (~400 nm).
2
Determine the relationship between wavelength and frequency using the wave speed equation c=λfc = \lambda f.
Frequency is inversely proportional to wavelength (f=cλf = \frac{c}{\lambda}).
Because electromagnetic waves travel at the speed of light in a vacuum, longer wavelengths correspond to lower frequencies and shorter wavelengths correspond to higher frequencies.
3
Sequence the given colors in order of increasing frequency.
Red light (lowest frequency) -> Yellow light -> Green light -> Violet light (highest frequency).
Following the ROYGBIV sequence, wave frequency increases continuously from red to violet.
