Question

a black t-shirt is warmer in the summertime than a white t-shirt because the black t-shirt

answer options:
select one of four

doesnt absorb red.
absorbs mainly violet light.
reflects all wavelengths of light.
absorbs all wavelengths of light.

Explanation:

To determine why a black T - shirt is warmer in summer, we use the concept of light absorption and reflection. Black objects absorb all wavelengths of light (which is converted to heat), while white objects reflect most light.

• Option 1: Saying a black T - shirt doesn't absorb red is wrong, as black absorbs all colors.
• Option 2: Black doesn't mainly absorb violet light; it absorbs all wavelengths.
• Option 3: Black does not reflect all wavelengths (white does that), so this is incorrect.
• Option 4: Black absorbs all wavelengths of light, which makes it warmer as the absorbed light is converted to heat.

Answer:

D. absorbs all wavelengths of light.
