Explain how a primary rainbow is formed
What will be an ideal response?
Answer: As sunlight enters a raindrop, it undergoes an initial refraction, with larger wavelengths being refracted less than shorter wavelengths. A small portion of the refracted light hits the back of the drop and is reflected. The reflected light is refracted a second time as it exits the drop at a lower position than when the first refraction occurred. The amount of total refraction is different for each wavelength and the familiar color separation results.
