Light Reflection & Vision

What is a common use of light reflection?

• Mirrors in bathrooms and cars use light reflection.

• Solar panels to absorb sunlight.

• Lenses in cameras to focus light.

• Windows to let in natural light.

Why do we see colors?

• We see colors because different surfaces reflect different wavelengths of light.

• We see colors because our eyes produce pigments that absorb light.

• We see colors because of the way our brain interprets sound waves.

• We see colors because of the temperature of the objects around us.

What is an example of a non-reflective surface?

• A mirror

• A carpet

• A glass window

• A polished table

What is the role of our eyes in vision?

• Our eyes receive light and send signals to our brain to create images.

• Our eyes only focus on objects without processing light.

• Our eyes are responsible for hearing and balance.

• Our eyes filter out colors and enhance brightness.

What is a simple way to demonstrate light reflection?

• Shining a flashlight on a shiny surface can demonstrate light reflection.

• Using a prism to split light into colors.

• Covering a mirror with a cloth.

• Bouncing a ball off a wall.

Which object does NOT use light reflection?

• A USB memory stick

• A mirror

• A glass window

• A piece of paper is an example of a surface that reflects light well.

• A wooden table is an example of a surface that reflects light well.

• A window is an example of a surface that reflects light well.

What is the difference between reflection and refraction?

• Reflection is when light bends as it passes through a medium, while refraction is when light bounces off a surface.

• Reflection is when light bounces off a surface, while refraction is when light bends as it passes through a medium.

• Reflection and refraction are the same phenomenon occurring under different conditions.

• Reflection is the absorption of light by a surface, while refraction is the scattering of light.

What is an example of light being reflected?

What is a practical application of light reflection?

• Lasers use light reflection to focus and direct light.

• Mirrors are used in telescopes to enhance visibility.

• Sunglasses use light reflection to reduce glare.

• Prisms are used to create rainbows in art.
