visible light has wavelengths between approximately 400 nanometers and 700 nanometers. write an absolute value equation that represents the minimum and maximum wavelengths in nanometers. use x to represent the wavelengths

The boundary equation is 400 ≤ x ≤ 700.

Step-by-step explanation:

Let x represents the wavelength in nanometers.

Maximum wavelength to have visible lights: 700 nanometers

Minimum wavelengths to have visible lights: 400 nanometers

The inequalities for these two boundary conditions would be:

400 ≤ x ≤ 700 nanometers

The absolute value equation would be:

|x - 400| > 0

|x - 700| > 0
