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

• Ancient China

• Ancient Greece

• Ancient Egypt

• Ancient Rome

What was the main issue with Huygens' wave theory of light?

• It couldn't explain the speed of light.

• It didn't account for light's straight-line propagation.

• It was not supported by any experiments.

• It failed to explain diffraction and interference.

What principle did Fermat extend in the 17th century regarding light?

• The principle of equal angles

• The principle of constant speed

• The principle of shortest time

• The principle of maximum distance

What causes the phenomenon of mirages?

• Diffraction of light around obstacles

• Interference of light waves

• Refraction due to varying refractive indices

• Reflection of light on smooth surfaces

What type of mirror has a real focus on the same side as the object?

• Flat mirror

• Convex mirror

• Concave mirror

• Spherical mirror

What is the main difference between convergent and divergent lenses?

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

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

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

• Convergent lenses are thicker than divergent lenses.

Why are large astronomical telescopes often built with mirrors instead of lenses?

• Mirrors provide better image quality.

• Mirrors are more durable than lenses.

• Mirrors are cheaper to produce.

• Building large mirrors is easier than building large lenses.
