Consider the following discussion between two students about the different properties of light. Student 1: I think I get how light works. If you look at the chart of electromagnetic spectrum, it shows that light with a lot of frequency will also have a long wavelength. But it all has the same speed. Student 2: I disagree. If one type of light has a high energy and a high frequency, it will have a faster speed than the light that has a lower energy and low frequency. Do you agree or disagree with either or both of the students? Explain your reasoning .

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
