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
