  1. 1. This explains why are the colours in the rainbow always in the same order.
    2. A rainbow is an optical illusion and is made by water and light.
    3. Sunlight is made up of white light which contains all the colours of the rainbow.
    4. When it hits the droplet all the colours appear.
    5. A refraction is when the the colours bend and split
    6. There is 7 colours in the rainbow red, orange, yellow, green, blue, indigo and violet.
    7. Because all the colours travels at different speeds when it hits the rainbow.
    8. Because they all travel at different speeds.
    9. That a rainbow is an optical illusion that you can never find the end of.

  2. Q1- it gives us a explanation of how rainbows are made.
    Q2- rainbows are made when sunlight hits the rain drop
    Q5- it’s when the light slows down when it enters the raindrop. Which makes it bend and split
    Q6- 7 colours names- red blue yellow indigo orange and violet.
    Q7- each of the colours have a wave length and that’s why they stay together.
    Q8- because it’s how it reflects from the raindrop and how the length is.
    Q9- I learnt that rainbows are made from raindrops and it’s because of the same length of the rainbow .

  3. 1. The BTN video explains what rainbows are and how they are made.

    3. Sunlight is made up of white light which contains all the colours of the rainbow.
    4. When the sunlight hits the droplet the sunlight slows down and seperates in to the different colours.
    5. A refraction is when the light enter the droplet and then sunlight bends and splits into the seven colours.
    6. There are 7 colours in a rainbow. The order of the colours is red, orange, yellow, green, blue, indigo and then violet.
    7. Each of the colours have a different wave length which is why they seperate.
    8. They are in that same order all the time because of how much they refract or bend in the droplet.

  4. 1. what is a rainbow.
    2. A rainbow is a optical illusion that you can never find the end of.
    3. Sun light is made of a white light which reflects all of the colours you can see.

    5. It is when the the colours hit and reflect of the droplets.
    6. 7 colours in the rainbow red orange yellow green blue indigo and violet.
    7. So the colours don’t over lap each other.
    8. Because the colours travel at different speeds.
    9. How the colours in a rainbow are formed.
