The refractive index for light of wavelength 400 nm passing through a type of glass is 1.470; when light of wavelength 750 nm passes through the glass the measured refractive index is 1.455. To what colours do these wavelengths correspond?
Olivia Askew400 nm = violet, 750nm=dark red.
Both are at the edge of human vision (or just beyond)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Why doe most telescopes use a primary mirror rather than an objective lens?
- What is the image formed by a concave lens?
- Why does the refracted ray bend away from normal on travelling from denser to rarer medium?
- Would the image of an object be the same if we put it in front of a convex mirror, and in front of a diverging lens if they have the same focal length? If not, what would be the differences? (Distance of the object is the same in both conditions.)
- When white light goes through the prism, it splits into a spectrum. Why red rays refract less and purple rays most of all?
