To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

<span>

</span>
<span>

λ

</span>⇒ λ

⇒ λ

⇒ <span>λ</span>
Answer:
Similarly, enzymes can only function in a certain pH range (acidic/alkaline). Their preference depends on where they are found in the body. For instance, enzymes in the intestines work best at 7.5 pH, whereas enzymes in the stomach work best at pH 2 because the stomach is much more acidic.
Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to significantly benefit a great many people, so it should not be considered immoral or risky is refers as scientific observation.
A scientist thinks that he might find serious inconsistencies in the fossil record if he conducts an excavation in a new location is refers scientific explanation because explanation is needed for it which can drawn from the scientific observation.
The rocks present in western Africa and eastern South America formed at the same place and at the same time is scientific observation because the scientists takes the data.
Even if modern organisms are found in ancient portions of the fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an exciting area of study, and more resources should be be devoted to it so it is refers as scientific explanation.
The age, type, and composition of ancient rocks in western Africa are nearly identical to the age, type, and composition of rocks in eastern South America is scientific observation which is taken by the scientist through research.
Answer:
Why is the air colder farther from the earth,you ask ?its easy
Explanation:
A pretty basic answer is that the farther away you get from the earth, the thinner and thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it gets cooler and cooler at higher elevations.
A new island is formed from a volcanic eruption is an event that lead to speciation.
<h3>What is speciation?</h3>
Speciation is the evolutionary process in which in populations of organisms come to being or evolve to become distinct species. The biologist Orator F. Cook made some Discovery and term it speciation in 1906when he performed experiment on cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.
Therefore, A new island is formed from a volcanic eruption is an event that lead to speciation.
