- 17. Sunlight of intensity I is incident on 4 ideal polarizers in series. The polarization axis of the first polarizer is not known, but it is known that each subsequent polarizer has a polarization axis 24° off from the one before it. What is the intensity of the light that exits the fourth polarizer?

What is the wavelength knowing the seawater has a refractive index of n= 1.34?1) A small spaceship cruises the solar system using an ideal, square absorbing solar sail with side length L = 1000 m. a. Assume the sun can be modeled as a point source of light. If the intensity of electromagnetic radiation near the earth is 1300 W/m^2 , and the earth is 150×10^9m from the sun, what is the power of the sun’s light emission? If this spacecraft is close to Mars, 230×10^9m away from the sun, and is traveling directly away from the sun with an acceleration a0 = 0.01m/s^2 what is the mass of the spacecraft? b. You fasten two adjustable light polarizers with polarizer axes that subtend an angle θ with respect to one another on the side of the sail where light is incident. These polarizers are the same size as the sail, covering its total area. What must θ be to reduce the acceleration of the craft to a0/8? What must θ be to reduce the acceleration of the craft to 0? c. Using the value of θ you found that corresponds to the acceleration of a0/8 find the magnitude of the…

- Light becomes partially polarized as it reflects off nonmetallic surfaces such as glass, water, or a road surface. The polarized light consists of waves vibrate in a plane that is ____________ (parallel, perpendicular) to the reflecting surface. Explain.The intensity of light decreases as the inverse square of the distance from the source. Does this mean that light energy is lost? Explain.The intensity I of light from an isotropic point source is determined as a function of distance r from the source. The figure gives intensity / versus the inverse square r2 of that distance. The vertical axis scale is set by Is = 223 W/m², and the horizontal axis scale is set by rs2 = 9.8 m2. What is the power of the source? I (W/m²) -² (m²)
- (a) A sheet of a certain type of glass is transparent but tinted red. To measure its light-absorbing properties, beams of monochromatic light from two different lasers are shined through the glass. One laser emits red light with a wavelength of 630 nm, while the other emits blue light with a wavelength of 460 nm. What is the frequency of the light emitted (in Hz) from each laser? red ? Hz blue ? Hz (b) The glass absorbs 73.0% of the energy of the blue light; that is, the intensity of the blue light just after exiting the glass is 27.0% of the intensity just before entering. (The sheet of glass is thin and the laser beam narrow, so the intensity change is not due to any widening of the beam.) Find the ratio of the amplitude of the blue light's electromagnetic wave before entering the glass to the amplitude after exiting the glass.
