Understanding Light Properties

What is light transmission?

• Light transmission is the passage of light through a material.

• Light transmission is the generation of light from a source.

• Light transmission refers to the absorption of light by a material.

• Light transmission is the reflection of light off a surface.

Which material allows most light to pass through?

• Opaque plastic

• Clear glass

• Wood

• Frosted glass

What happens to light when it hits a black surface?

• Light is reflected off the black surface without any change.

• Light is absorbed by the black surface, converting it into heat.

• Light is scattered in all directions by the black surface.

• Light passes through the black surface completely unaltered.

Define light absorption.

• Light absorption is the process by which matter absorbs photons, converting light energy into other forms of energy.

• Light absorption is the process of light traveling through a vacuum.

• Light absorption is the emission of photons from matter.

• Light absorption is the reflection of light by matter.

What type of material is known to block all light?

• Opaque material

• Translucent material

• Reflective material

• Transparent material

What is an example of a translucent material?

• Wood

• Plastic wrap

• Clear glass

• Frosted glass

How does light behave when it hits a mirror?

• Light is absorbed by the mirror and does not reflect.

• Light passes through a mirror without any change.

• Light bends and changes direction when hitting a mirror.

• Light reflects off a mirror according to the law of reflection.

What is the difference between opaque and translucent materials?

• Opaque materials block all light; translucent materials allow some light to pass through but obscure visibility.

• Opaque materials allow some light to pass through; translucent materials block all light.

• Opaque materials are transparent; translucent materials are completely clear.

• Opaque materials allow light to pass through; translucent materials block all light.

Can light pass through water? Why or why not?

• Yes, but only if the water is still and clear.

• Yes, light can pass through water.

• No, light is absorbed by water completely.

• No, light cannot pass through water because it is opaque.

What is the role of color in light absorption?

• Color determines which wavelengths of light are absorbed or reflected by an object.

• Color only affects the brightness of an object.

• All colors absorb light equally.

• Color has no effect on light absorption.
