The Sun has a power of P = 3.85 x 1026 Watts. The Earth is a distance of (on average) 1.49 x 108 km away from the Sun. A solar sail is a distance R = 2.00 x 107 km away from the Sun. What pressure does the light exert on the sail? You can assume that the sail is not being blocked by the Earth in anyway. You can assume the system is completely reflective. Make sure to put your answer in terms of mPa (milliPascal) and include appropriate significant figures. Your Answer: Answer units

An isotropic point source emits light at wavelength 470 nm, at the rate of 210 W. A light detector is positioned 450 m from the source. What is the maximum rate dB/dt at which the magnetic component of the light changes with time at the detector's location? The speed of light is c = 3 x 108 m/s, and Ho = 47 x 107 H/m. Number 2.98754 UnitsTT/s the tolerance is +/-5%

10. A beam of light polarized along the y axis and moving along the +z axis passes through two polarizing sheets with axes of polarization oriented 30° and 70° measured clockwise from the positive direction of the y axis. The final intensity of the beam is found to be 61 W/m². What is the initial beam intensity? (1) 280 W/m² (2) 700 W/m² (3) 200 W/m² (4) 50 W/m² .2 (5) 140 W/m² 11. Light of wavelength 520 nm is incident perpendicularly on a diffraction grating having 200 lines/mm. What is the highest

A beam of initially unpolarized light passes through a sequence of three ideal polarizers. The angle p12 between the axes of the first and second polarizers is 23.9°, and the angle p23 between the axes of the second and third polarizers is 58.7°. P12 P23 What is the ratio of the intensity I3 of light emerging from the third polarizer to the intensity Io of light incident on the first polarizer? I3 0.2256 Io Incorrect

Experiments show that the ground spider Drassodes cupreus uses one of its several pairs of eyes as a polarization detector In fact, the two eyes in this pair have polarization directions that are at right angles to one another Suppose linearly polarized light with an intensity of 775 W/m² shines from the sky onto the spider and that the intensity transmitted by one of the polarizing eyes is 774 W/m². For this eye, what is the angle between the polarization direction of the eye and the polarization direction of the incident light?

Yellow light with wavelength 600nm propagates in the +x direction. The wave is linearly polarized along the ±y direction. a) Draw a labeled snapshot mode picture of what the electric and magnetic fields look like. Use vector representation. b) Determine the frequency of oscillation of the electric field vector for the yellow light. Is the magnitude of this frequency very large or very small?

Electromagnetic Plane Waves: In infrared optical systems germanium is often used to form optical components. For infrared wavelengths, germanium can be considered lossless, non-magnetic (u- 1) and has a relative dielectric constant e 16. Consider a plane wave inside a piece of germanium incident at the interface between germanium and air. The plane wave is polarized parallel to the plane of incidence and the angle of incidence is halfway between the Brewster angle and the critical angle for total internal reflection. Germanium: Air: H1 = Ho i E1 = 16e, H2 = Ho i €2 = €o %3. Be A, a) What is the angle of incidence? b) What are the reflection and transmission coefficients for the wave at this angle of incidence?

A.) Polarized light is incident on 6 polarizing sheets. The axis of the first polarized sheet makes an angle 0 with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle e from that of adjacent sheets. Find e if 34% of the incident intensity is transmitted by the sheets. B.) Suppose you want to rotate the plane of polarization of a beam of polarized light by 78°, but you do not want the final intensity to be less than 53% of the initial intensity. What is the minimum number of polarizing sheets you must use? Assume that each sheet is rotated the same angle relative to the adjacent sheets. sheets
