Question 4 (1 point)
Carla's favorite ball is bright blue when it is outside in the direct sunlight. When she is inside, the ball appears to be almost green. Why does Carla's ball seem to change colors?

a
Color is determined by the temperature of an object, and the temperature changed when Carla went inside out of the sunlight.
b
Color is determined by the size of an object, and Carla's ball lost air while being played with, so it was smaller when she went inside.
c
Color is determined by the density of an object, and Carla's ball became more dense when she went inside out of the sunlight.
d
Color is determined by the wavelength of light reflected or absorbed by the object, and the light changed when Carla went inside.

Answer 1

d

Color depends on the wavelengths of light an object reflects. The illumination changed (sunlight vs indoor lighting), so the spectrum reaching Carla's eye changed and the ball looked more green indoors.
