Given that a rainbow forms when sunlight reflects off raindrops at different angles. Here, the process of reflection occurs. According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
For the blue light, the measure of angle 2 is 40 degrees. Here the law of reflection will be used. So, the measure of angle 1 is as same as 40 degrees.
To check your answer to a problem you will start with the answer you got when you divided times the answer to the problem, will give you the number you started with.
