Chapter 16.1, Problem 9SSC

To determine

To Explain:The reason why we might choose a window shade that is translucent and opaque.

Explanation of Solution

Introduction:

Translucent material enables the passing of partial light through it, and but an opaque object does not allow light to pass through. This is the main difference between translucent material and opaque material.

Since translucent material does allow the light to pass through it, hence when light is required to transmit through the window shade, translucent material should be used. On the other hand, if when light is not required to pass through the window shade, then opaque window shades should be used.

Conclusion:

Hence, translucent material is used to pass the light through the window and opaque material is used not to pass the light through the window shades.
