all the following are correct about the visible light portion of the electromagnetic spectrum, except:
white light separates into all the colors of the rainbow when put through a prism.
the visible light spectrum comprises all the red, orange, yellow, green, blue, indigo, and violet.
the visible light portion of the electromagnetic spectrum is the only part humans can see.
violet has the longest wavelength and the highest frequency waves.

Explanation:

1. Analyze each option:

• Option 1: White light passing through a prism disperses into the colors of the rainbow (ROYGBIV), so this is correct.
• Option 2: The visible light spectrum includes red, orange, yellow, green, blue, indigo, violet, so this is correct.
• Option 3: Visible light is the portion of the electromagnetic spectrum visible to human eyes, so this is correct.
• Option 4: In the visible spectrum, violet has the shortest wavelength and highest frequency, while red has the longest wavelength and lowest frequency. So this statement is incorrect.

Answer:

Violet has the longest wavelength and the highest frequency waves.
