In the ocean, the photic zone is the region where there is sufficient light for photosynthesis to occur. (See the figure below.) For marine phytoplankton, the photic zone extends from the surface of the ocean to a depth where the light intensity is about 1% of surface light. Consider a region of the ocean where the depth of the photic zone is about D = 22 meters. In this region of the ocean, by what percentage does light intensity decrease for each additional meter of depth? (Round your answer to two decimal places.)

If you have completely polarized light of intensity 150 W/m2 , what will its intensity be after passing through a polarizing filter with its axis at an 89.0 angle to the light’s polarization direction?
At the end of Example 17, it was stated that the intensity of polarized light is reduced to 90.0% of its original value by passing through a polarizing filter with its axis at an angle of 18.4° to the direction of polarization. Verify this statement.
A water break at the entrance to a harbor consists of a rock barrier with a 50.0-m-wide opening. Ocean waves of 20.0-m wavelength approach the opening straight on. At what angles to the incident direction are the boats inside the harbor most protected against wave action?
A Michelson interferometer is used to measure the wavelength of light put through it. When the movable mirror is moved by exactly 0.100 mm, the number of fringes observed moving through is 316. What is the wavelength of the light?
Two polarizing sheets P1 and P2 are placed together with their transmission axes oriented at an angle to each other. What is when only 25% of the maximum transmitted light intensity passes through them?
Under what conditions can light be modeled like a ray? Like a wave?
When light is incident normally on the interface between two transparent optical media, the intensity of the reflected light is given by the expression S1=(n2n1n2+n1)2S1 In this equation, S1 represents the average magnitude of the Poynting vector in the incident light (the incident intensity), S1 is the reflected intensity, and n1 and n2 are the refractive indices of the two media. (a) What fraction of the incident intensity is reflected for 589-nm light normally incident on an interface between air and crown glass? (b) Does it matter in part (a) whether the light is in the air or in the glass as it strikes the interface?
If a polarizing filter reduces the intensity of polarized light to 50.0% of its original value, by how much are the electric and magnetic fields reduced?
The attenuation of light in water is dependent on the extinction coefficient (eλ) summed for all wavelengths.What factors contribute to or determine this extinction coefficient?
A beam of light is emitted from a source that is submerged in a fluid with an index of refraction of 4.27. What minimum angle (in degrees) must the beam make with "normal" in order to achieve total reflection of the beam at the interface of the fluid surface and the air above?
The intensity L(x) of light x feet beneath the surface of the ocean satisfies the differential equation dL/dx=-kL. From experience, a diver knows that diving to 19 ft in a sea cuts the intensity in half. He cannot work without artifical light when the intensity falls below one-fifth of the surface value. About how deep can he expect to work without artifical light? round to the nearest tenth
A light ray enters the atmosphere of the Earth and descends vertically to the surface a distance h = 100 km below. The index of refraction where the light enters the atmosphere is 1.00, and it increases linearly with distance to have the value n = 1.000 293 at the Earth’s surface. (a) Over what time interval does the light traverse this path? (b) By what percentage is the time interval larger than that required in the absence of the Earth’s atmosphere?
