Refraction and Light Behavior Concepts

The video explores activities that demonstrate the phenomenon of refraction, such as changing arrow directions, bending straws, and altering lemon sizes in water. It explains how refraction occurs when light travels between different media, causing it to bend. The video also highlights real-life applications of refraction, including camera lenses, human eyes, and optical instruments like binoculars and microscopes.

What phenomenon is responsible for the magical activities demonstrated in the video?

• Reflection

• Diffraction

• Refraction

• Dispersion

What happens to the direction of the arrows when water is poured into the glass?
