Understanding Mirror Reflections

The video explores why mirrors appear to flip images horizontally but not vertically. It explains that mirrors actually flip images in the Z direction, causing confusion. The video uses examples like raising hands and reading text to illustrate this concept. It also discusses how our perception of mirror images is influenced by symmetry and daily experiences, such as reading text on t-shirts. The conclusion is that mirrors show what is presented to them, and the perceived horizontal flip is due to how we present objects to the mirror.

Why do mirrors appear to flip images horizontally but not vertically?

• Because our eyes perceive horizontal flips more easily.

• Because mirrors are designed to only flip horizontally.

• Because mirrors have a special horizontal flip function.

• Because we present objects to mirrors in a way that causes a horizontal flip.

What is the main reason mirrors do not flip images vertically?

• Because vertical flips are not possible in mirrors.

• Because we do not present objects in a way that causes vertical flips.

• Because our eyes cannot perceive vertical flips.

• Because mirrors are designed to prevent vertical flips.

What happens when you turn a piece of paper with text towards a mirror?

• The text appears horizontally flipped.

• The text appears upside down.

• The text appears vertically flipped.

• The text appears unchanged.

What is the Z-direction flip in mirror reflections?

• A flip that occurs when you move an object sideways.

• A flip that occurs when you move an object up and down.

• A flip that occurs when you move an object forward and backward.

• A flip that occurs when you rotate an object.

What happens when you point an arrow forward towards a mirror?

• The reflection points forward.

• The reflection points backward.

• The reflection points to the left.

• The reflection points to the right.

How does our symmetry affect our perception of mirror images?

• It makes us see mirror images as distorted.

• It makes us see mirror images as unchanged.

• It makes us see mirror images as horizontally flipped.

• It makes us see mirror images as vertically flipped.

How can you make a left-handed glove appear as a right-handed glove in a mirror?

• By flipping it vertically.

• By flipping it horizontally.

• By rotating it.

• By flipping it front to back.

Why do we often perceive text on t-shirts as flipped in mirrors?

• Because mirrors have a special function for t-shirts.

• Because t-shirts are designed to be flipped.

• Because our eyes are used to seeing flipped text.

• Because we put them on in a way that flips the text.

What is a common misconception about mirror reflections?

• That mirrors flip images vertically.

• That mirrors do not flip images at all.

• That mirrors flip images horizontally.

• That mirrors distort images.

What is the effect of doing a handstand in front of a mirror?
