Chapter 34: Q. 6 (page 990)

The mirror in FIGURE EX34.6 deflects a horizontal laser beam by 60∘. What is the angle ϕ?

Short Answer

Expert verified

Angle of the laser beam,ϕ=30°

Step by step solution

01

The Law of Reflection

The incident and reflected rays are parallel to the surface and within the same plane.

θi=θr

02

Estimate the values

In FIGURE 34.6, a horizontal beam strikes the mirror and deflects it by 60degrees.

When we are asked to calculate the angle supported the geometry of the figure, we notice that

θi+ϕ=90°⟶θi=90°-ϕ

θr+60°-ϕ=90°⟶θr=90°-60°-ϕ

03

Find the Angle

θi=θr, In keeping with the rule of reflection. so,

90°-ϕ=90°-60°-ϕ

ϕ=60°-ϕ

2ϕ=60°

ϕ=30°
