Which of these is an example of energy transfer by radiation?
a. sand burning the soles of the feet
b. a handle of a frying pan heating up an electric stove
c. hands rubbed together to become warm
d. a surfer feeling warm as sunlight shines on her
I would have said D. Surfer feeling warm as sunlight shines on her. This is because sunlight is made up of electromagnetic waves/radiation which can warm her as the sun emits infrared radiation and other waves such as visible light.
