Luminance

The video explains how brightness is perceived based on the amount of light passing through a given area. It highlights that the same amount of light appears brighter when emitted by a smaller object compared to a larger one, due to higher luminance.

What is the term used to describe light passing through a given area?

• Reflection

• Brightness

• Luminance

• Refraction

How does the size of an object affect the brightness of light it emits?

• Size does not affect brightness

• Smaller objects appear brighter

• Larger objects appear brighter

• Both appear equally bright

What happens to the perceived brightness when the same amount of light is emitted by a smaller object?

• It becomes invisible

• It remains the same

• It appears brighter

• It appears dimmer

Which object has a higher luminance?

• Both have the same luminance

• Depends on the material

• A smaller object

• A larger object

Why do smaller objects have higher luminance?

• They absorb less light

• They reflect more light

• They concentrate light in a smaller area

• They emit more light
