Which of the following is NOT true about light waves?

1. Heat from the sun is a type of light wave
2. Human eyes can only see a limited range of light waves
3. All light waves have the same frequency
4. Light waves come in a spectrum of wavelengths

3. All light waves have the same frequency

Explanation:

That is wrong. If all light waves had the same frequency, everything would be weird and different.
