H.W: If a (10 mJ) laser pointer creates a spot that is 5 mm in diameter in a 30 second, determine the radiation pressure on a screen that absorbs 40% of the light that strikes it.A disturbance passes through the Sun's corona (e.g. a CME) and produces radio emissions that are observed at Earth. Calculate the emission frequency if it originates from a region where the electron density is 108 cm-3, the temperature is 1.5 MK, and the magnetic field strength is 10-4 Gauss. Report your answer in MHz to 2 significant digits.
- The initials "FM" stand for frequency modulation. When broadcasting a radio wave, the constant frequency "B" in our problems becomes a varying quantity, f(t), such that Y= Asin[2pieF(t)]t. This causes the waves to have an inconsistent wavelength. The FCA assigns eah radio station a "band-width" around an assigned frequency in megahertz, MHz, which is simply a million waves/seond. For example, 98.7 is allowed to let it's frequencies vary slightly about/below 98.7 MHz. A. Suppose a FM radio station is assigned an equation of y=Asin[2pie(93,200,000 + 10,000sin 500piet)]t. What is the assigned frequency in MHz? B. Give the minimum and maximum frequencies of the FM radio station over time. C. If you've ever hanged stations while traveling, you may have been able to hear 2 FM stations at the same time. Explain how this can happen.What is the energy of a photon if it's frequency is 1.00s-1?What is the energy in cm- of a photon of 500 nm energy that may be observed in electron (UV-VIS) spectroscopy? What is the energy of a 6-micron photon typical in IR spectroscopy? What is the energy of a photon absorbed in a typical CO rotation microwave line (6 × 10'Hz)?
- Scientists use laser range finding to measure the distance to the moonwith great accuracy. A very brief (100 ps) laser pulse, with a wavelengthof 532 nm, is fired at the moon, where it reflects off an array of 100 4.0-cm-diameter mirrors placed there by Apollo 14 astronauts in 1971. The reflected laser light returns to earth, where it is collected by a telescope and detected. The average earth-moon distance is 384,000 km. The laser beam spreads out on its way to the moon because of diffraction, reaching the mirrors with an intensity of 300 W/m2. The reflected beam spreads out even more on its way back because of diffraction due to the circular aperture of the mirrors.a. What is the round-trip time for the laser pulse to travel to the moon and back?b. If we want to measure the distance to the moon to an accuracy of 1.0 cm, how accurately must the arrival time of the returning pulse be measured?c. Because of the spread of the beam due to diffraction, the light arriving at earth from one…10 Im Young's double feremce pattem is obtaimed dight t waveleng Th bilt experiment, an mtere sereen by a on a comisg frem certain dark fringe tormed.
