Answer:
Distance, d = 274.05 meters
Explanation:
It is given that,
The time taken by the laser light to reflect off the building and arriving is, [tex]t=1.827\times 10^{-6}\ s[/tex]
We need to find the distance between the building and you. Let the distance between the person and the building during thee process of reflection and come back is 2d. So,
The speed of light is c is calculated as :
[tex]c=\dfrac{2d}{t}[/tex]
[tex]d=\dfrac{ct}{2}[/tex]
[tex]d=\dfrac{3\times 10^8\times 1.827\times 10^{-6}}{2}[/tex]
d = 274.05 meters
So, the building is 274.05 meters far from you. Hence, this is the required solution.
