Abeam of light is polarized in a vertical plane and has an intensity i0. the beam passes through an ideal polarizer and then through an ideal analyzer whose axis is set horizontally. if the axis of the polarizer is set at 60° with the vertical, what is the ratio of the intensity of the final beam to i0?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?
