Correct answer: A. Reflectors
- A. Reflectors
- B. Absorbers
- C. Radiators
- D. Emitters
Explanation
White clothes are worn on hot days or in hot climates because they are good at reflecting sunlight. Light-colored and especially white fabrics reflect a significant portion of the sun's rays, helping to keep the body cooler. This is because lighter colors absorb less heat compared to darker colors. The reflection of sunlight reduces the absorption of thermal energy, contributing to a cooler feeling when wearing white clothes in hot weather.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
