A sine function increasing through the origin can be used to model light waves. Violet light has a wavelength of 400 nanometers.
andrew11 [14]

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 400:4=100 nanometers.

The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
