The Solution:
The question says a typical human eye can see light within the 430 to 770 THz range.
We are asked to write out the compound inequality that represents the situation.
So, we shall represent the length a human eye can see with x.
That means x is greater than 430 THz but less than 770 THz.
Therefore, the required compound inequality is
[tex]430Thus,
the correct answer is 430
