The appearance of color is a result of the absorption and reflection of certain wavelengths of light. a shirt appears a certain color because it reflects that color of light. on the other hand, a shirt appears black when it absorbs all wavelengths of light and white when it reflects all wavelengths of light. how will sunlight most likely affect a black shirt on a hot summer day? a) the temperature of the shirt will depend on how much sunlight is diffracted around the shirt. b) the temperature of the shirt will not change because the sunlight is transmitted through the shirt to the body. c) the temperature of the shirt will decrease because most of the light is reflected off of the shirt. d) the temperature of the shirt will increase because all wavelengths of light are absorbed by the shirt.
