Akrypton laser produces a cylindrical red laser beam 2.40 mm in diameter with 1.70 w of power. what is the light intensity 1.76 m away from the laser?

Explanation:

Given that

Diameter of laser beam d= 2.4 mm

Radius of laser beam r= 1.2 mm

Power P =1.7 W

We know that intensity(I) of laser beam given as follows

Now by putting the values

So

So the intensity at 1.76 m away from laser

the answer is b i think

answer

the arrows to the right of earth should point up.
