Question: 3 . ( 5 ) A holiday light display contains red and green LEDs. Each LED uses 9 0 mW of power, and assume it

3.(5) A holiday light display contains red and green LEDs. Each LED uses 90 mW of power, and assume it is \(50\%\) efficient at turning that into light. How many photons per second are emitted from the red LED compared to the green LED? (Hint: this will use one of the wildest conjectures in physics when it was first made, the birth of quantum theory. Thank you Dr. Planck!)
