Dan placed three colored gels over the main spotlight in the theater so that the intensity of the light on stage was 900 watts per square centimeter (W/cm2). After he added two more gels, making a total of five over the spotlight, the intensity on stage dropped to 600 W/cm2. What will be the intensity of the light on stage with six gels over the spotlight if you know that the intensity of light decays exponentially with the thickness of material covering it?
