A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment,
a scientist used two colorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?
Given that a colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading.
Though consistent, the first colorimeter has a zero error of -5.
Hence whenever first calorimeter is used this adjustment to be made i.e. actual reading +5 should be made to get correct reading
But second can be used as such taking the reading as correct.
In drastic reduction, what is being described above is the process called the founder effect. The founder effect is also the other term called in which it applies the definition above. This is made when a population has been created with the means of having small numbers and not too many individuals.
Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.
Electromagnetic waves do not require a medium to travel through space without a medium. Electromagnetic waves can travel through air, vacuum of space and solid materials.
