Visual Science and Optical Illusions Quiz

What is 'apparent motion'?

• The way objects move in space.

• A trick of the eye where still images appear to move.

• The movement of stars in the night sky.

• A new dance trend.

Flip-books create the illusion of motion by:

• Using mirrors and light.

• Changing colors rapidly.

• Showing a series of still images in quick succession.

• Using electronic screens.

Which is a common type of optical illusion?

• Magic tricks.

• Mirages in the desert.

• Pictures that seem to move or change as you look at them.

• A delicious looking cake that turns out to be fake.

Why do optical illusions confuse our brain?

• Because our brains are too slow.

• Due to the brain interpreting visual information in unexpected ways.

• They are only confusing to animals, not humans.

• They use special paints.
