A carbon-dioxide laser emits infrared light with a wavelength of 10.6 μm.     Part A What is the length of a tube that will oscillate in the mmm = 210000 mode?     Part B What is the frequency? Express your answer with the appropriate units.     Part C 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?

Part C Rank each wire-mass system on the basis of its fundamental frequency. Rank from largest to smallest. To rank items as equivalent, overlap them. ▸ View Available Hint(s) largest AB c]D]E F The correct ranking cannot be determined. Submit Reset Help smallest

Parts B and D are the only problems I need help with

Tmax Amin = 380nm = 380x1 & min=- M 1 max: 700hm - 700x 10-9. f max= 300×10= 1.895 3x108 = 4.286x Amin 700x10 V=N 1 Frequency range: 4.286 x 1014 -7.895x1014 f = * 듯 3. One type of radar works by sending a pulse out to and object and timing how long it takes for the pulse to return after bouncing off of the object. If the radar is tracking a plane 100 km away, how long does it take from the time the pulse leaves the radar to the time it returns? 16X374 + 3.33x10 4. Radar antenna tend to be of comparable size to their wavelength. The radiation used by radar ranges from 300 Mhz to 15 Ghz. a. What is the range of wavelengths? b. If the antenna dimensions are comparable to the wavelength of the radiation used, what will be the approximate size range of antenna used for radar? 3 =
