Practice Question

1.Describe the following terms

a.Transparent

A transparent material can transmit light all the way through the material. 

b.Translucent

A translucent material will allow some light to pass through the object, but the light is scattered or refracted as it passes through the material.

c.Opaque

2. Explain how frosted glass windows prevent a person from seeing clearly through the glass.

Frosted glass is a translucent material, so when light passes through the glass it is scattered and refracted. The rays of light that enter our eyes are not from a clear source, so we cannot distinguish the objects on the other side of the frosted glass.

3. Would colourless jelly be classed as transparent, translucent or opaque?

Translucent as it tends to scatter light rays.
