Answer:

Statement that is true about electromagnetic and mechanical waves is:

Option B: Mechanical waves must travel through a medium, but electromagnetic waves do not require a medium to travel.

Explanation:

'Electromagnetic' waves do not need any medium to travel whereas 'mechanical waves' need a medium or matter for transmission. Electromagnetic waves are produced by the 'vibrations' of the charged particles. They can even travel in vacuum.  

On the contrary, mechanical waves are caused by the 'wave amplitude'. Mechanical wave can travel in solid, liquid and gas and are considered to be periodic disturbance.

Thus, Option B is the most statement apt explaining the difference between electromagnetic and mechanical waves.

Explanation:

Culture is always influenced by people's ideas and it keeps changing due to many reasons. They may change due to migration of people from one place to another because of trade or invasion.

Anthropology means studying different traits or characteristics of a human in present societies and what existed in the past. Anthropologists who study all the traits of human culture, varying from violence, war to love and how different people understand the same from different parts of the world are known as Cultural anthropologists.  

Cultural relativism means understanding a person's beliefs and values based on that person's own culture and not judging them for those beliefs and practices based on another beliefs. So, to make cultural relativism as research study, anthropologists must try to understand that person's beliefs within their own cultural context.
