The colours, so as of accelerating wavelength, are: crimson, orange, yellow, inexperienced, blue, indigo, and violet.
This sequence is commonly remembered utilizing the acronym ROYGBIV.
λ = pace of sunshine / frequencyThe pace of sunshine is roughly 299,792,458 meters per second (m/s) in a vacuum. The frequency of sunshine is measured in Hertz (Hz). When gentle passes from one medium to a different, its pace decreases, inflicting the frequency to extend, and vice versa. This is named the Doppler impact.
Do you know {that a} rainbow consists of seven vibrant colours, each distinctive and charming? Whereas admiring the fantastic thing about a rainbow, cooking a tasty meal may be simply as satisfying.

If the refractive index of the fabric is excessive, the sunshine will bend extra, making a higher dispersion of colours. This is the reason rainbows usually seem behind water droplets within the air, as water has a excessive refractive index.
- Water
- Glass
- Diamond
- Oil
| Materials | Refractive Index |
