Answer:30
Step-by-step explanation:
Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is
nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
X times 2x=50
2x^2=50
Divide by 2
X^2= 25
X=5
Length is 10 ft
