🌈What is VIBGYOR Full Form and other information

 

VIBGYOR


🌈 VIBGYOR Full Form

VIBGYOR stands for the sequence of colors seen in a rainbow:

  • V – Violet

  • I – Indigo

  • B – Blue

  • G – Green

  • Y – Yellow

  • O – Orange

  • R – Red

It represents the visible colors of light arranged by increasing wavelength (and decreasing frequency).


🎨 About VIBGYOR (Visible Spectrum)

  • Visible Light Spectrum is the portion of the electromagnetic spectrum that human eyes can detect.

  • It ranges approximately from 380 nanometers (nm) (violet) to 750 nanometers (nm) (red) in wavelength.

  • These colors are naturally seen in a rainbow due to dispersion of light (splitting of white light by water droplets).


📈 Frequency, Wavelength, and Speed

Color Wavelength (nm) Frequency (THz)
Violet ~380–450 ~668–789
Indigo ~450–475 ~631–668
Blue ~475–495 ~606–631
Green ~495–570 ~526–606
Yellow ~570–590 ~508–526
Orange ~590–620 ~484–508
Red ~620–750 ~400–484

Notes:

  • Wavelength (λ) and frequency (f) are inversely proportional:
    f=cλf = \dfrac{c}{\lambda}

  • Where:

    • cc = speed of light ≈ 3 × 10⁸ m/s

    • λ\lambda = wavelength in meters

    • ff = frequency in Hz (Hertz)

Speed of light (c) is constant in vacuum:
👉 3 × 10⁸ meters/second

In materials (like water, glass), light slows down slightly depending on refractive index.


🌈 Spectrum of Light (Position of VIBGYOR)

The Visible Spectrum lies between:

  • Infrared (longer wavelength than red light) and

  • Ultraviolet (shorter wavelength than violet light).

👉 Light spectrum order by wavelength (smallest to largest):
Gamma rays → X-rays → Ultraviolet → Visible (VIBGYOR) → Infrared → Microwaves → Radio waves


⚡ Key Facts about VIBGYOR

  • Dispersion: White light splits into VIBGYOR when passing through a prism.

  • Rainbow: Natural phenomenon showing VIBGYOR due to reflection, refraction, and dispersion.

  • Energy: Violet has the highest energy (short wavelength, high frequency), Red has the lowest energy (long wavelength, low frequency).
