47. The loudness of sound depends on its a) wavelength b) frequency c) amplitude d) all of these
[B][I]c) amplitude[/I][/B]
Well I am totally disagreed with this answer as the loudness of the sound not only depends upon amplitude rather on wavelength and frequency as well.
The greater the wavelength, frequency and amplitude is, the higher/louder the sound would be.

According to the Society of Clinical Psychologists, clinical psychologists are extensively trained in the assessment and diagnosis of psychological disorders, but may also help patients suffering from minor adjustment disorders or other problems. See they have little to do with treatment. Psychiatrists on the other hand are mental health professionals and licensed medical doctors who provide assessment, diagnosis and treatment of mental health disorders.
