In reality, the index of refraction of a material depends on the wavelength of the light. In other words, the index of refraction of water is a little bit different for each color of light. This is a property called dispersion. Use what you have learned in this activity, and research a bit online, to describe the process by which a rainbow forms. How is refraction involved in this process?
Homework Answers
From this we can conclude that when white light pases from any medium in atmosphere ,that medium will have some refractive index
When white light pass which Is combination of seven colour
And each colour have different wavelengths
So according to wavelengths each light deviated at some some which are not same and hence we see all colours in rainbow

Constants SOLUTION Light rays that enter your eye are affected by the fluid that fills the eyeball, called the vitreous humor (Figure 1). When red light from a l = 633 nm helium-neon laser enters your eye, its wavelength drops to 474 nm. Use this information to calculate the index of refraction of the vitreous humor and the speed and frequency of light passing through it.

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
