Question
Chapter 29, Problem 47A
To determine
To Explain: A secondary rainbow is dimmer than the primary bow.
Expert Solution & Answer
Answer to Problem 47A
After the double reflection, ray of light loses its energy. So, secondary rainbow is dimmer than the primary bow.
Explanation of Solution
Introduction: Angle of reflection is equals to angle of incidence. Also, the law of reflection applies to both, totally reflected waves and partially reflected.
Explanation: Rainbow is a spectacular illustration of dispersion. A secondary rainbow develops when light entering a raindrop undergoes two internal reflections instead of just one. Also, a secondary rainbow is dimmer than the primary bow because intensity of the light is diminished by the extra internal reflection.
Conclusion: A secondary rainbow is not as bright as a primary rainbow.
