2.A ray of light strikes a surface and is reflected so that the angle between the incident ray and the reflected ray is 30 degrees. What is the angle of reflection?

Answer : ______ degrees (just input the number)

Answer 1

1.

$$\text{angle of incident=angle of reflection}=\dfrac{30\degree}{2}=15\degree$$

$$\text{angle of incident}=\colorbox{aqua}{$15$}\degree$$

2.

$$\text{angle of incident=angle of reflection}=\dfrac{30\degree}{2}=15\degree$$

$$\text{angle of reflection}=\colorbox{aqua}{$15$}\degree$$
