Light incident on a glass sheet is partly reflected and partly refracted. how is the reflected ray different from the refracted ray?

the refracted ray is unpolarized whereas the reflected ray is horizontally polarized.

the refracted ray is unpolarized whereas the reflected ray is vertically polarized.

the refracted ray is horizontally polarized whereas the reflected ray is
unpolarized.

the refracted ray is vertically polarized whereas the reflected ray is unpolarized.

the refracted ray is vertically polarized whereas the reflected ray is horizontally polarized.

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Which configuration would produce an electric current? a) rotate a coil of copper wire between two magnets. b) connect a wire between a copper and zinc strip sitting in a beaker of water. c) connect a wire to the (+) positive end of a battery and the other end to a light bulb. d) connect a wire to the negative end of a battery and the other end to a light bulb.

Afrequency generator sends a 550 hz sound wave through both water and ice. what is the difference in wavelength between the wave produced in ice and the wave produced in water?
