Prior to Einstein's paper, electromagnetic radiation such as visible light was considered to behave as a wave: hence the use of the terms "frequency" and "wavelength" to characterise different types of radiation. The energy transferred by a wave in a given time is called its intensity. The light from a theatre spotlight is more intense than the light from a domestic lightbulb; that is to say that the spotlight gives out more energy per unit time and per unit space(and hence consumes more electricity) than the ordinary bulb, even though the colour of the light might be very similar. Other waves, such as sound or the waves crashing against a seafront, also have their own intensity. However, the energy account of the photoelectric effect didn't seem to agree with the wave description of light.
What other types of wave besides light has its own intensity?
sound

Ethical commitments in anthropology include noticing and documenting genocide, infanticide, racism, mutilation (including circumcision and subincision), and torture. Topics like racism, slavery, and human sacrifice attract anthropological attention and theories ranging from nutritional deficiencies to genes to acculturation have been proposed, not to mention theories of colonialism and many others as root causes of Man's inhumanity to man. To illustrate the depth of an anthropological approach, one can take just one of these topics, such as "racism" and find thousands of anthropological references, stretching across all the major and minor sub-fields.
Why can one find thousands of anthropological references to the topics?
