Answer:
x= 2.7734 m
Explanation:
Given the angle of incidence θ= 33.0°
distance from laser point and mirror = 1.10 m
laser point is 1.80 m above the floor
let the distance between mirror base and laser beam striking the floor after reflection = x
figure has been attached and from the from the figure we can write
[tex]tan\theta= \frac{1.80}{x}[/tex]
[tex]tan33\degree= \frac{1.80}{x}[/tex]
[tex]tan33\degree= 0.649[/tex]
putting value and solving we get
x= 2.7734 m
