Answer:
Scientists have been debating over light being a wave or particle since its recognition.
Sir Issac Newton discovered that light had frequency and other properties. Newton described light to be a particle because it created shadows which were sharp and very clear.
Francesco Maria Grimaldi, claimed that light was a wave. This was because this scientist observed the diffraction of light and hence, claimed light to be a type of wave.
The speed of light is 299 792 458 m / s. Nothing can travel faster than light.

Answer:
Group B
Explanation:
<u>The fish in group B are those in the control group.</u>
<em>A control group during an experiment represents a group of the subject that is subjected to all experimental variables except the independent variable - the manipulate-able variable that is supplied by the experimenter which directly affects the dependent variable. </em>
In this case, the independent variable is the type of food given to the two groups of fishes - microwaved or regular food while the dependent variable is the time it takes for the fishes to swim through the maze. Since the focus of the experiment is to see if microwaved food enhances the swimming speed of fishes, the group of fish that receives microwaved food would represent the treatment group while those that received regular food would be the control group.
Hence, group B represents the control group.
