How do Venetian blinds allow for light control?

1. The angle of the slats can be adjusted.

2. They consist of vertical slats that can be pulled aside.

3. They are made of rigid panels that cannot be adjusted.

4. They are fixed and cannot be moved.

The correct answer is: The angle of the slats can be adjusted.

Venetian blinds offer effective light control primarily through the adjustable angle of their horizontal slats. By tilting the slats, occupants can regulate the amount of light entering a space, allowing for flexibility in brightness and glare reduction. This functionality is particularly beneficial because it enables users to customize the light levels according to their preferences and the time of day, enhancing comfort and usability in various settings. The ability to adjust the slat angle contrasts sharply with designs that are either fixed or constructed from rigid materials, which would not allow for light manipulation. Thus, the adjustable nature of the slats is what makes Venetian blinds a popular choice for managing natural light within interior spaces.
