The evidence is tested repeatidly to ensure it produces the same results of idenitifcation and comparison. If the same result is produced, it is considered reliable. A test must be sensitive in the sense that it identifies the unique characteristics of the sample. For example, a DNA test can identify people based on their unique DNA. Finally, tests are specific if they identify particular substances. A test would be specific if it identified the presence of a particular drug, like cocaine, with no other drugs giving the same result.
Answer:
So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy.
