La óptica y los sistemas ópticos

The video explores the nature of light, covering historical theories from ancient times to the 17th century, including Euclid's and Newton's ideas. It discusses the wave and particle theories, highlighting contributions from Young, Fresnel, and Maxwell. The video explains reflection, refraction, and Snell's law, and describes phenomena like mirages. It covers types of reflection, spherical mirrors, and the role of lenses in optical instruments. Finally, it examines wave phenomena such as interference and diffraction, and how light behaves in different media.

Which ancient civilization is known for creating mirrors almost 4000 years ago?

• Ancient Egypt

• Ancient India

• Ancient China

• Ancient Greece

What was the main issue with Newton's corpuscular theory of light?

• It didn't account for light's wave properties.

• It suggested light was affected by gravity.

• It proposed light traveled in curves.

• It couldn't explain the speed of light.

According to Fermat's principle, what does light do when it travels between two points?

• Takes the path of maximum distance

• Takes the shortest time path

• Takes the path of least resistance

• Takes the longest path

What causes the phenomenon of a mirage?

• Reflection of light on a smooth surface

• Refraction of light due to temperature gradients

• Diffraction of light around obstacles

• Interference of light waves

What is the main difference between convergent and divergent lenses?

• Convergent lenses focus light to a point, divergent lenses spread light out.

• Convergent lenses are thicker, divergent lenses are thinner.

• Convergent lenses are used in telescopes, divergent lenses in microscopes.

• Convergent lenses are made of glass, divergent lenses of plastic.

Why do large astronomical telescopes often use mirrors instead of lenses?

• Mirrors are cheaper to produce.

• Mirrors provide better image quality.

• Mirrors can be made larger than lenses.

• Mirrors are lighter than lenses.

Why does the sky appear blue during the day?

• Blue light is scattered more than other colors.

• Blue light is absorbed by the atmosphere.

• Blue light is emitted by the sun.

• The ocean reflects blue light into the sky.
