Question

___Scenario Suppose that Ray- Ban is considering a new line of sunglasses that would be sold in major department stores. The new line would be positioned as a more distinctive brand than the typical glasses sold through department stores, and would be priced higher than otheer brands in the store, but a lower price line than current Ray- Ban lines that are sold through more selective stores. In determining the price for this sunglass line, ray-ban wants to gather information about all brands sold in department stores and about customers' perceptions of those brands.

Answer 1

To check if sunglasses are polarized, overlap two pairs and rotate them; light should be blocked at two specific positions due to the polarization effect. This test confirms the presence of a chemical filter that aligns molecules in the lenses to selectively allow or block light waves.

Step-by-step explanation:

When considering purchasing polarized sunglasses, there is a simple test one can perform to verify their polarization. If you place one pair of sunglasses in front of another and rotate one of the pairs, you should see the light passing through them to get blocked at two positions, approximately 90 degrees apart. This phenomenon is due to the polarization of light, which filters out glare from horizontal surfaces by allowing only vertically aligned light waves to pass through the lens.

The process works because polarized lenses have a special chemical applied to them that filters light. The chemical's molecules are lined up specifically to block some of the light from passing through the lens. When two polarized lenses are placed in front of each other and rotated, the angles of these molecular alignments change relative to each other, leading to points where they cancel each other out and block light, hence showing the sunglasses are indeed polarized.
