Refractive Index - Part 3 - The Reversing Arrow Trick

The video demonstrates an experiment to highlight the refractive index using simple materials. It explains how light bending causes an arrow to appear reversed when viewed through a glass of water. The video provides step-by-step instructions for the experiment and explains the concept of focal distance and focal point.

What is the main focus of the video titled 'Refractive Index Part 1, The Reappearing Penny'?

• A demonstration of the refractive index using a penny

• A detailed explanation of the refractive index

• An introduction to optical illusions

• A discussion on the history of optics

Which of the following items is NOT needed for the refractive index experiment?

• Safety goggles

• A tall transparent glass

• A marker

• A blank piece of white paper

What should you do after drawing an arrow on the paper for the experiment?

• Pour water on the paper

• Place the paper inside the glass

• Center the arrow behind the glass

• Draw another arrow on the glass

What happens to the arrow when the water is poured into the glass?

• It disappears completely

• It changes color

• It becomes larger

• It reverses direction

Why does the arrow appear to reverse direction when viewed through the glass?

• Due to the reflection of light

• As a result of the glass shape

• Because of the water temperature

• Because of the refractive index
