Reflection and Ray Model of Light Formula and Example

Reflection and Ray Model of Light Formula :

The Reflection and ray model of light formula is θ 1(d)  in degree is equal to the product of reflection of light θ 2 (d) in degree. Hence the reflection and ray  model of light formula can be written as

θ 1 (d)2(d)

Sample Problems :

Example 1 :

Calculate the angle would it be reflected? In a ray of light strikes a surface at an angle of 70° to the normal.

Solution :

Since, θ1 = θ2 as per the law of reflection.

Here, θ1 = 70°

⇒ θ2 = 70°

Example 2 :

Calculate angle would it be reflected? In a ray of light strikes a surface at an angle of 150° to the normal.

Solution :

Since, θ1 = θ2 as per the law of reflection.

Here, θ1 = 150°

⇒ θ2 = 150°
