Question

In the given figure, the angle of reflection is

  1. 30°    
  2. 60°    
  3. 45°    
  4. none of these    

The correct answer is: 45°


    fraction numerator d y over denominator d x end fraction equals 2 x
    At open parentheses fraction numerator 1 over denominator 2 end fraction comma fraction numerator 1 over denominator 4 end fraction close parentheses t a n invisible function application theta equals 1 comma theta equals 45 to the power of ring operator end exponent
    Angle of incidence = Angle of reflection = 45°
