Question

In the adjoining figure, AB represents the incident ray, and BK is the reflected ray. If angle BCF = θ, then ∠BFP is given by ______.

 

Options

• θ

• 2θ

• 3θ

• 2.5θ

Answer 1

In the adjoining figure, AB represents the incident ray, and BK is the reflected ray. If angle BCF = θ, then ∠BFP is given by 2θ.

Explanation:

∠BFP = θ + ∠CBF

= θ + r = θ + θ

= 2θ
