Acarbon-dioxide laser emits infrared light with a wavelength of 10.6 μm. what is the length of a tube that will oscillate in the m = 16 mode? imagine a pulse of light bouncing back and forth between the ends of the tube. how many round trips will the pulse make in each second?

The length of a tube and number of rounds are 0.848 m and .

Explanation:

Given that,

Wavelength

m = 160000

We need to calculate the length

Using formula of wavelength

Laser tube behave like closed pipe

Distance traveled by pulse of light in one back and fourth trip

We need to calculate the time

Using formula for time

We need to calculate the number of round

Using formula of number of round

Hence, The length of a tube and number of rounds are 0.848 m and .
