Luces, sombras y reflejos

What is the speed of light in a vacuum?

• 299,792,458 meters per second

• 1,000,000 meters per second

• 100,000 meters per second

• 500,000 meters per second

Explain the difference between transparent, translucent, and opaque objects.

• Opaque objects allow light to pass through completely

• Transparent objects allow light to pass through completely, translucent objects allow some light to pass through, and opaque objects do not allow any light to pass through.

• Transparent objects absorb all light

• Translucent objects do not allow any light to pass through

Describe the properties of light.

• Light travels in zigzag patterns and cannot be reflected or refracted.

• Light is a form of solid matter that cannot be absorbed by any material.

• Light is a form of sound waves that can be heard by the human ear.

• Light is a form of electromagnetic radiation that behaves like a wave and a particle. It travels in straight lines, can be reflected, refracted, and absorbed by different materials.

How are shadows formed?

• When an object blocks the path of light, creating an area of darkness behind it.

• Shadows are formed when there are no clouds in the sky

• Shadows are formed when an object reflects light

• Shadows are formed when the sun is directly overhead

What is rectilinear propagation of light?

• Light travels in straight lines

• Light travels in spiral paths

• Light travels in zigzag patterns

• Light travels in random directions

Explain the concept of reflection in mirrors.

• When light is absorbed by a smooth surface

• Reflection occurs only in opaque surfaces

• When light bounces off a smooth surface and changes direction

• Reflection is caused by the color of the object

Give an example of an opaque object.

• A clear water bottle

• A brick wall

• A transparent plastic bag

• A glass window

How does light interact with translucent objects?

• Translucent objects absorb all the light that passes through them.

• Translucent objects scatter the light in different directions.

• Translucent objects emit their own light when exposed to other light sources.

• Translucent objects have no effect on the light that passes through them.

What are the laws of reflection?

• Angle of incidence is greater than the angle of reflection

• Angle of incidence is less than the angle of reflection

• Angle of incidence is unrelated to the angle of reflection

• Angle of incidence is equal to the angle of reflection

Why do we see our reflection in a mirror?

• Light reflects off the mirror's surface

• Our reflection is projected onto the mirror

• The mirror emits our reflection

• The mirror absorbs our image
