To determine

To Explain: Whether the customer is being reasonable of she wants see the dress in the daylight instead of fluorescent lightning.

Explanation of Solution

Introduction: 

The fluorescent lamp emits discrete spectrum of light in small range of frequencies which means it produces limited amount of colors. The fluorescent lamp is a mixture of different gases such as mixture of argon and mercury.

The fluorescent lamp can illuminate more space with less power consumption. So, the fluorescent lamps are used in shops, offices, and stores for illumination.

Explanation: 

Dresses act as a filter of light when the fluorescent light falls on the dress. The actual color may not be visible because some colors are not reflected by fluorescent lamp. The sunlight reflects all the colors and the actual color of the dress is visible.

Conclusion: 

Yes, the customer is reasonable because in sunlight, actual color of dress will be visible.
