What is the first step in using a pipette according to the provided instructions?

• Carefully attach the pipette filler to the 25cm³ glass pipette

• Place the tip of the pipette into the water

• Use the roller on the pipette filler to draw water into the pipette

• Fill the pipette past the top line (graduation mark)

What is white light made from?

• A) A single wavelength of light

• B) Lots of different wavelengths of light

• C) Only red and blue wavelengths of light

• D) Only green and yellow wavelengths of light

What name do we use to help us remember the colours present in white light?

Why do we see colours?

• Because of the reflection and absorption of light by different surfaces.

• Because of the emission of light by different surfaces.

• Because of the refraction of light by different surfaces.

• Because of the diffraction of light by different surfaces.
