- Please asapPhysics Polarization: Write down the equations of an unpolarized E field before it hits a linear polarizer that is polarized in the x-direction. What are the E field equations after the linear polarization? I'm having extreme difficulty on this problem, need some guidance.In the figure, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of 0 = 35°, 02 = 25°, and 03 = 34° with the direction of the y axis. What percentage of the light's initial intensity is transmitted by the system? Number i Units
- An ideal polarizing sheet transmits 90% of the incident partially polarized light. The polarizing sheet is now rotated through 45 degrees; during the rotation process the transmitted light monotonically decreases in intensity. What fraction of the incident intensity now passes? O a. 0% O b. between 40% and 90% O c. Between 50% and 80% O d. 50% O e. Between 0 and 50%Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.65. What time in nanoseconds is required for a signal to travel 0.17 m through such a fiber? nsA life-guard wants your help choosing a pair of new sun-glasses to minimize reflections from the water. She noticed an advertisement that let one choose the angle of polarization orientation of the sunglasses. What polarization angle, if any would you advise her to choose for her new glasses. Question 6 options: A pair of polarizing sunglasses offers no advantage for a people near the water. Sunglasses with a horizontally oriented polarizer would be best for reducing ocean glare. Sunglasses with a vertically oriented polarizer would be best for reducing ocean glare.
- Two sheets of ideal polarizing material are placed with their transmission axes at 60.0 to each other. A third polarizing sheet is placed between them with its transmission axis at 30.0° to the axes of the other two. What is the fraction of the incident light intensity that is transmitted, when the middle sheet is removed? ___I0Polarized light passes through two rotated filters from left to right, as shown. At the point A, its intensity is Io. The polarization axis of the first polarizer makes an angle 01= 52.6° with the direction of polarization the incoming light. The polarization axis of the second polarizer makes an angle 02= 59.6° degrees with the polarization axis of the first polarizer. E Polarized В light The intensity of light at the point C is: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?
- ** 46. How much unpolarized light gets through a polarizer? Unpolarized light is as likely to have its polarization vector in one direction as another. Therefore, on average, the up-down component of the polarization vector for unpolarized light will be the same as the right- left component. These equal components in two perpendicular directions are in the same relationship as the E-field components when polarized light hits a polarizer with its polariza- tion vector at 45° to the optic axis. We can use this connection to find out what fraction of the energy in an incident unpolarized beam makes it through the polarizer as polarized light. a) If an electric field vector of a polarized light beam is 45° to the optic axis of the polar- izer, find the ratio between the magnitude of the electric field vector that passes through the polarizer and the magnitude of an incident polarized electric field vector. This will be the same as the ratio of the magnitude of the electric field of the…A.) Polarized light is incident on 5 polarizing sheets. The axis of the first polarized sheet makes an angle with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle from that of adjacent sheets. Find if 40% 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 82°, but you do not want the final intensity to be less than 57% 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. sheetsElectromagnetic 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?
