It was field day at school. the sun was bright and the temperature high. most of the students wore light colored t-shirts to stay cool because dark colors most wavelengths found in white light.

Absorbs.

Explanation:

Hello,

In this case, we consider that sunlight makes up of a mix of all visible wavelengths of electromagnetic spectrum. It has been substantiated that when all visible wavelengths get into the eye at once, the color white is perceived. However, the absence of any light is related with the black color.

In such a way, black it is said to absorb the radiation while white reflects it, therefore, when the sun is shining, providing high temperatures, it is recommended to wear light colored T-shirts.

Therefore, the answer is:

"It was field day at school. The sun was bright and the temperature high. Most of the students wore light colored T-shirts to stay cool because dark colors absorbs most wavelengths found in white light."

Best regards.
