Lunar astronauts placed a reflector on the Moon’s surface, off which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. (a) To what accuracy in meters can the distance to the Moon be determined, If this time can be measured to 0.100 ns? (b) What percent accuracy is this, given the average distance to the Moon is 384,480 kin?

What are the wavelengths of (a) X-rays of frequency 2.01017 Hz? (b) Yellow light of frequency 5.11014Hz ? (C) Gamma rays of frequency 1.01023Hz ?

EMFT For a electromagnetic wave of 3GHz frequency, what wavelength will be required for the same microwaves.

A laser pointer (as shown in the figure below) supplies an output power of P = 3.78e-03 Watts at a wavelength of λ = 6.37e-07 meters. The light is contained in a spot of radius r = 1.06e-03 meters. Watt/m² Joules/m³ Determine the intensity of the light, I = Determine the energy density, u = Determine the RMS Electric Field strength ERMS = Volt/meter Determine the force applied to an object that PERFECTLY REFLECTS this light, F = Newtons

Frequency range: 4.286x10¹4 -7.895x10 F = ** 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? 2/4 V + 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? 5. When used for imaging, the wavelength of the radiation needs to be smaller than the thing being imaged. To a get a pretty good idea of what kind of radiation is needed to image something assume that the wavelength must be the size of the object or smaller. With this in mind, would visible light work well to image protozoa with a…

What is the wavelength of the electromagnetic wave emitted by the oscillator–antenna system if L= 0.253 mH and C = 25.0 pF?

He–Ne lasers are often used in physicsdemonstrations. They produce light of wavelength 633 nm and a powerof 0.500 mW spread over a cylindrical beam 1.00 mm in diameter(although these quantities can vary). What is the intensity of this laser beam?
