Question

about racism ...........​

Answer 1

Explanation:

Racism takes many forms and can happen in many places. It includes prejudice, discrimination or hatred directed at someone because of their colour, ethnicity or national origin.

People often associate racism with acts of abuse or harassment. However, it doesn’t need to involve violent or intimidating behaviour. Take racial name-calling and jokes. Or consider situations when people may be excluded from groups or activities because of where they come from.

Racism can be revealed through people’s actions as well as their attitudes. It can also be reflected in systems and institutions. But sometimes it may not be revealed at all. Not all racism is obvious. For example, someone may look through a list of job applicants and decide not to interview people with certain surnames.

Racism is more than just words, beliefs and actions. It includes all the barriers that prevent people from enjoying dignity and equality because of their race.

Atmospheric Refraction

================================

Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air, decreasing with increased density.
