Question

these are light waves. which one will have the brightest light? they are the same brightness but different colors

Explanation:

The brightness of a light wave is related to its amplitude (height of the wave), and the frequency (number of waves) relates to color. The three light waves here have the same amplitude (since their peak - to - trough height relative to the grid is the same), so their brightness is the same, and differences in wave patterns (like frequency) correspond to different colors.

Answer:

They are the same brightness but different colors
