- 3. Electromagnetic waves from a radio station pass through an open window of a house. The square window has side length 0.75 m and the waves pass through perpendicular to the window's area. The electric field is measured at the window and found to be 0.02 V/m. In air, we can use the vacuum permeability = 4 x 10-7 H/m. (i) What is the magnitude of the Poynting vector, S, for the radio waves passing through the window? (ii) How much energy do the radio waves carry through the window during a 2-minute-long broadcast of BBC Radio 4's shipping forecast? [Hint: think of the units of S [units = (J/s)/m²] and Energy [units = J].Unpolarized light passes through two Polaroid sheets. If the transmission axisbetween the sheets is 30° what fraction of the original unpolarized light is transmitted through the second Polaroid sheet?a) 1/2b) 2/3c) 3/4d) none of these17 An unpolarized beam of light (intensity I0) is moving in the x-direction. The light passes through three ideal polarizers whose transmission axes are (in order) at angles 0.0°, 54.0°, and 18.0° counterclockwise from the y-axis in the yz-plane. If the polarizer in the middle is removed, what is the intensity and polarization of the light transmitted by the last polarizer? _____/0
- 6. In a polarizer-analyzer combination, 90.0% of the light intensity falling on the analyzer is absorbed. Determine the angle between the transmission axes of the polarizer and analyzer.** 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…
