The Journey Of Light Waves And Their Impact On Our World

The video explains how light travels in waves and straight lines, and how it interacts with objects through reflection, absorption, and refraction. It describes the properties of transparent, translucent, and opaque materials, and explores various applications of light in technology, such as lenses, lasers, and optical fibers.

How does light primarily travel through space?

• In a zigzag pattern

• In circular motions

• In random directions

• In waves and straight lines

What happens to light when it hits a shiny surface?

• It reflects

• It passes through

• It gets absorbed

• It disappears

Why can we see objects in the dark?

• Because they are transparent

• Because they absorb light

• Because light reflects off them

• Because they emit their own light

What is the effect called when light bends as it passes through water?

• Reflection

• Diffusion

• Refraction

• Absorption

What type of object allows some light to pass through but not all?

• Opaque

• Translucent

• Reflective

• Transparent

Which material is considered opaque?

• Clear glass

• Plastic wrap

• Aluminum foil

• Wax paper

What is a sundial used for?

• To measure temperature

• To tell time using shadows

• To focus light

• To reflect light

How do lenses help us see better?

• By blocking light

• By absorbing light

• By bending light

• By reflecting light

What is one use of laser lights?

• To reflect light

• To create shadows

• To absorb light

• To cut through materials

What technology uses bundles of thin strands to carry information?

• Sundials

• Mirrors

• Optical fiber cables

• Telescopes
