The diagram depicts a black object X that is at constant temperature. The arrows show thermal radiation being absorbed and emitted at the surface. Object Y has the same constant temperature as X and is the same in every other respect except that its surface is white. Which row gives the correct comparison between object X and object Y?
- Arate of absorption for X higher; rate of emission for X higher
- Brate of absorption for X lower; rate of emission for X higher
- Crate of absorption for X higher; rate of emission for X lower
- Drate of absorption for X lower; rate of emission for X lower
