Light Nature

What is reflection of light?

• Reflection of light is the process where light bounces off a surface, changing direction but not its wavelength.

• Reflection of light is the absorption of light by a surface.

• Reflection of light is the bending of light waves around an object.

• Reflection of light is the emission of light from a source.

Explain the concept of refraction of light.

• Refraction of light is the absorption of light by a medium

• Refraction of light is the reflection of light off a surface

• Refraction of light is the scattering of light in all directions

• The concept of refraction of light involves the bending of light as it passes from one medium to another due to a change in its speed.

How are colors of light produced?

• Colors of light are produced by the different wavelengths of light.

• Colors of light are produced by temperature changes.

• Colors of light are produced by mixing paint colors.

• Colors of light are produced by sound waves.

What causes shadows to form?

• Blocking of light by an object

• Refraction of light by an object

• Absorption of light by an object

• Reflection of light by an object

Differentiate between transparent and opaque materials.

• Opaque materials are always see-through.

• Transparent materials absorb light, while opaque materials reflect light.

• Transparent materials allow light to pass through, while opaque materials block light.

• Transparent materials are heavier than opaque materials.

Give examples of light sources.

• Moon

• Flashlight

• Sun, light bulbs, candles, fire

• Stars

What type of surface reflects light in a regular manner?

• Dull and matte surface

• Smooth and polished surface

• Transparent surface

• Rough and bumpy surface

Why does a straw appear bent when placed in a glass of water?

• Diffraction of light

• Absorption of light

• Reflection of light

• Refraction of light

What happens when white light passes through a prism?

• Dispersion of white light into its component colors

• White light remains unchanged after passing through the prism

• Reflection of white light off the prism

• Absorption of white light by the prism

How does the color of an object affect the light it reflects?

• The color of an object has no impact on the light it reflects

• The color of an object changes the speed of light it reflects

• Objects of different colors reflect the same light

• The color of an object affects the light it reflects by absorbing certain wavelengths of light and reflecting others.
