How do polarizing sunglasses reduce the glare from the road? explain.

Answer

Polarization is a method of restricting different plane of transverse waves into the required plane.  

Polarization process is done with the help of Polaroids. Polaroids are kept at different angles, these angles are selected according to the wave requirement. Polaroids allows only waves which are aligned to it.

so, this phenomenon is the same in case of polarizing sunglasses as it restricts the unwanted sun waves to pass through it.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
