If y<span>ou are going to invent a new device that people can use instead of a microwave oven to warm up leftovers, the type of electromagnetic wave that would be most useful to investigate would probably be infrared waves, because these kinds of waves are associated with heat. </span>

A krypton 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

marta [7]

Answer:

$I=3.75\times 10^5 W/m^2$

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

$I=\dfrac{P}{\pi r^2}$

Now by putting the values

$I=\dfrac{P}{\pi r^2}$

$I=\dfrac{1.7}{\pi \times 0.0012^2}$

$I=3.75\times 10^5 W/m^2$

So the intensity at 1.76 m away from laser

$I=3.75\times 10^5 W/m^2$
