¿Qué es el reflejo?

The video tutorial explains the concept of light reflection, highlighting how different surfaces reflect light differently. Dark or matte surfaces absorb most light, while rough surfaces scatter it. Smooth, glossy surfaces are highly reflective, with mirrors being a prime example due to their construction with a silver layer. Mirrors reflect light in a single direction, allowing us to see reflections clearly. They are used in various applications, such as in dentistry, to view areas not directly visible.

What happens to light when it hits a dark or matte surface?

• It is mostly absorbed.

• It is completely reflected.

• It is scattered in all directions.

• It passes through the surface.

How do rough surfaces like sand and stone affect light?

• They scatter light in multiple directions.

• They absorb all the light.

• They do not interact with light.

• They reflect light in one direction.

What makes mirrors highly reflective?

• Their dark color.

• The layer of shiny silver beneath the glass.

• Their rough surface.

• The absorption of light.

Why can you only see your face in a mirror when directly in front of it?

• Because mirrors are transparent.

• Because mirrors only reflect light from the front.

• Because mirrors absorb light from other angles.

• Because mirrors scatter light in all directions.

How do mirrors help dentists in their work?

• By absorbing light to reduce glare.

• By being transparent to see through them.

• By scattering light to illuminate the entire mouth.

• By reflecting light to see areas not directly visible.
