Photochemical smog results from the interaction of the ultraviolet portion of sunlight and ozonee, nitrogen oxides and reactive hydrocarbons. The NOX can result from emissions from combustion sources such as car engines, the reactive hydrocarbons are also attributable to car exhaust. The ozone can come from the sunlights action on atmospheric oxygen, stratospheric ozone downwasing or chemical reactions in the atmosphere wirth NOx. The outcome is an excess of ozone, and polyaromatic hydrocarbons of several types.
Smog is a kind of air pollution; the word "smog" is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.

photo as a prefix means light. Photochemical smog is when sun light reacts with Nitrogen oxides and other organic compounds, forming dangerous levels of 03 at ground level.
London-type smog forms when particles in coal smoke combine with water droplets in humid air.

Photochemical smog is caused by the action on chemicals of sunlight.
photochemical smog is formed by a complex process . photochemical smog irritates breathing passages, plants, and damage rubber,plants,and some plastics

No. Quite the opposite, in fact. Photochemical smog is formed when emissions and other chemicals react with the suns rays.

New Zeland is famous for its photochemical smog.
Photochemical smog is a type of smog made when hydrocarbons and nitrogen oxides mix with sunlight.
Photochemical smog is caused by the action on chemicals of sunlight.
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.

Photochemical smog can occur most anywhere. London-type smog comes from factories and the burning of coal and fossil fuels, where photochemical smog comes from hydrocarbons and nitrogen oxides mixing with sunlight.
