1. Analyse why red sunsets can sometimes be more impressive when there is more dust or pollution in the air than usual.  When there is more dust or pollution in the air, red sunsets can be more impressive because when the red light in the atmosphere spreads and gets hit by light particles, there are more particles in the air which means that the light travelling from one particle to the other has a smaller distance between particles which means a stronger colour is retained

1. Describe what happens inside water droplets to cause a rainbow and explain how you can tell whether a rainbow is a primary or secondary.

When it rains, the light refracts inside the water  droplets which makes the spectrum of light appear (rainbow).

Secondary rainbows are very rare and are when a second rainbow occurs in the sky. You can tell the difference because on a secondary rainbow the colours are backwards with Violet on the outside and red on the inside.
