The colors of the visible spectrum can be correlated with their corresponding frequencies because the wavelength and frequency of light are inversely related through the speed of light. The speed of light ((c)) in a vacuum is approximately (3 \times 10^8) meters per second. The relationship between wavelength ((\lambda)), frequency ((f)), and the speed of light is given by:
[ c = \lambda \cdot f ]
To find the frequency, you can rearrange this formula to:
[ f = \frac{c}{\lambda} ]
Using this relationship, we can calculate the frequency range for each color in the visible spectrum. Here are the frequency ranges for each color:
-
Red:
- Wavelength: 620–750 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{750 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{620 \times 10^{-9} \text{ m}} )
- Frequency range: 400–484 THz
-
Orange:
- Wavelength: 590–620 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{620 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{590 \times 10^{-9} \text{ m}} )
- Frequency range: 484–508 THz
-
Yellow:
- Wavelength: 570–590 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{590 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{570 \times 10^{-9} \text{ m}} )
- Frequency range: 508–526 THz
-
Green:
- Wavelength: 495–570 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{570 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{495 \times 10^{-9} \text{ m}} )
- Frequency range: 526–606 THz
-
Blue:
- Wavelength: 450–495 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{495 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{450 \times 10^{-9} \text{ m}} )
- Frequency range: 606–668 THz
-
Violet:
- Wavelength: 380–450 nm
- Frequency: ( f = \frac{3 \times 10^8 \text{ m/s}}{450 \times 10^{-9} \text{ m}} ) to ( f = \frac{3 \times 10^8 \text{ m/s}}{380 \times 10^{-9} \text{ m}} )
- Frequency range: 668–789 THz
Thus, as the wavelength decreases from red to violet, the frequency increases, which corresponds to the energy of the photons increasing across the visible spectrum.
not that unusual, mass shootings appear before gun control bills, Palestinian riots show up before anti Semitics laws pushed, terrorist attacks before wars and bill that dissolve American freedoms, pandemics before elections and bill that hand over power to WHO, it goes on and on
Media: in a strange black swan event 10 Boeing employees die after a flight crash carrying all 10, the employees were flying on a 247 Airbus when the wings suddenly fell off and the plane fell into the ocean killing all 10 passengers
yes it is lol
